DAB Digital Radio Sound Quality – Make Your Own Mind Up

This appeared in my inbox, via Google. I have no idea of its provenance whatsoever. It’s a montage of DAB digital radio stations in London (taken yesterday allegedly, but there’s some inconsistencies there). The stated aim is to allow people to make their own mind up between the variety of services and the sound quality that they are broadcast in.

I’m not sure why it’s ordered the way it is (I couldn’t detect a pattern to the order), but most of the “big brand” stations are towards the end of the 15 minutes.

So go have a listen to what DAB Digital Radio in London sounds like, and make your own mind up.

CES – The Radio Perspective

CES Welcome Screen

I was lucky enough to visit The Consumer Electronics Show this year. CES lies at the very heart of the consumer electronics industry, and is a bellwether for the health of consumer spending and consumer interests. I went to go and see how radio fits into this frenetic and fast-moving world.

CES is vast. Truly awe-inspiringly vast. 140,000 delegates, thousands and thousands exhibitors, spread across tens of thousands of hall space across three huge venues. I mean, you may think it’s a long way down the road to the chemist, but that’s just peanuts to CES. (with apologies to Douglas Adams). Your chances of seeing it all are slimmer than a whelks chance in a supernova (ditto). But one does ones very best, and wears comfortable shoes (the very best tip I got from reading the blogosphere)

CES has the whole spectrum of consumer electronics providers – from the powerhouses of Samsung, LG, Microsoft, Intel, Motorola, Panasonic – to hundreds and hundreds of booths in a shanty town like arrangement representing the manufacturing communities of China and Taiwan.

Bill Gates (Microsoft) and Paul Otellini (Intel) both devoted large segments of their Keynote speeches to the future of Digital Entertainment (and a quick bash on Guitar Hero for Bill, and a bloke called Slash). Sweeping presentations and brilliant visuals emphasised a seamless entertainment experience in the home, the car and the mobile device. TV – yep. Films – you got ’em. Music – sure thing. Radio… Hello, hello, paging radio – is radio in the house? Apparently not. Oh well. (Otellini’s speech started with a reworking of The Buggles, Video Killed The Radio Star which rather fell over when people realised that video hasn’t actually killed the radio star – but hey, it was a great 80’s start to the show).

So where was radio amongst the vast shiny stands of the world’s major consumer electronics brands. Not present. Largely, I guess, because radio isn’t cutting edge techsexy. (Although I’ve no idea what LG were thinking of when inventing Mobile Pedestrian Handheld “MPH”, and attempting another flogging session of the dead horse of mobile TV). Does Microsoft’s Mediaroom (their IPTV platform) support radio; well, they weren’t sure, but it does do music. How about Microsoft Media Center (sic) – same response. Slightly better news at the Zune stand, where they recognised that lack of streaming support was a bit of a negative, and said there was a roadplan.

Nokia was good. They were demonstrating streaming radio on the N95 and Capital 95.8 streamed faultlessly first time. They talked about bringing together the Visual Radio and Streaming Radio into a single client, which is an exciting prospect. And they really joined in with the enviro/green theme of the show (which must have had a dedicated, and doubtless coal-fired, power plant. Amusingly the local coal lobby was running adverts on the local radio stations about how important and how much cleaner coal was nowadays. Yeah, yeah).

Most of the brand MP3 players have FM radio chucked in as an afterthought. It adds headcount, but nothing very exciting or revolutionary for the radio industry. iRiver were the notable exception, demoing their excellent little B20 device (which has the most comprehensive DAB Digital Radio implementation ever seen, on any device, anywhere) alongside their new W7 and W10 wifi enabled devices. Cowon also demo’ed a MP3+DAB radio unit. But where are Creative, Apple?

So, what about WiMax – to some people, the solution for broadcast radio to the masses? XOHM is the US implementation of WiMax, and they had a great theme driven stand. I asked which theme radio fitted into, and they thought it would probably be the “in the car” theme. But the “in the car” team hadn’t thought about radio. They thought it probably would work because mobile TV works over WiMax, but they promised to have a think about it and get back to me. Seems like the admiration between radio and WiMax isn’t mutual.

So far, the picture looks a bit glum. In a show driven by innovation in consumer electronics, there’s not much radio brings to the party. But let’s go deeper, and talk to the people on the stands.

Most the product managers I was able to talk to were quite interested in the idea of a new kind of radio. In essence, they were saying – give us something new to talk about, and we’ll include it. Logitech and Sonus talked about how their streaming devices can support visualisation, extended information, and interactivity – but no radio station has ever come and asked them about it. I spent some time with the folks from HD Radio, and they talked about how well the iTunes Tagging concept had been received, and demo’ed their natty media player device. Sirius and XM both had impressive stands showing of their range of own brand devices. Radio can do innovation, but apparently only when it’s done by new entrants; it would seem that legacy businesses find it awfully hard to get their heads round anything other than today and yesterday.

The other astonishing hit of the show, in terms of ubiquity, was Digital Picture Frames. They were simply everywhere, despite being described by one wag as “21st Century Lava Lamps”. I predict that an awful lot of homes will have them, and the manufacturers are already trying to differentiate themselves. Some have WiFi, some have Bluetooth, some play MP3s to accompany the pictures. But hang on, if it can play MP3, why not DAB digital radio? Isn’t the Kitchen Radio of the future actually a nifty 7″ digital picture frame, that shows Slideshow when you’re listening to the radio, and shows your favourite pictures when you’re not. Why, hey – now there’s an opportunity. (And a new Slideshow spec will be out shortly).

I was really pleased to be able to meet Jack Schofield of The Guardian in Vegas. We literally bumped into each other on the strip, and used the opportunity to have a really good discussion about DAB Digital Radio. Readers of both our outputs know that my responses have been tart at times, but I hope that the time we spent having an interesting and wide-ranging chat affirms with Jack that there’s no personal animosity, and that everyone on the Digital Radio project has a real passion for radio and that we do the very best we can with the resources and freedoms we have.

One final observation, and this is more to do with radio programming than digital radio. Vegas is the home of the 80’s pop hit. Music is piped everywhere – streets, lobbies, casino floors, restaurants, lifts. Not once, and I mean not one single time in a 6 day stay, did I hear anything other than pop hits from the 1980’s. Nu Shooz, I Can’t Wait; Falco, Der Kommisar; El Debarge, Who’s Johnny…. Given that Vegas is a multi-million dollar industry that is heavily researched, I believe that 80’s pop hits must make people happy, must make people spend lots of money, and therefore must be the sleeper hit format for digital radio in 2008.

There’s a flickr stream of my CES photos here.

Nick travelled with bmi from Manchester to Vegas, who were lovely, even if they caught a 5 hour delay on the way back. You have to love a British airline that serves clotted cream tea, cornish pasties and cottage pie, and brings the tea round before the coffee.

Core – A DAB Digital Radio Paradox

Core Mug

It was with a bit of a heavy heart that I said “so long (and thanks for all the fish)” to Core last night. The fresh hits station that I launched on 15th November 1999 finally fell silent at midnight. It’s always depressing when a radio brand is outlived by its mugs, stickers and headed notepaper.

Core was intended to be commercial radio’s response to Radio 1 – talking to late teenagers/early twentysomethings entering a more sophisticated and independent phase of their life, but still enjoying fresh hit music pumped out with enthusiasm and energy.

But Core never fulfilled its potential, falling victim to a paradox that looms over any attempt to modernise and evolve radio for the digital media world.

DAB Digital Radio in the UK only really got going towards the end of the later 1990’s when commercial radio committed substantial investment to building networks and starting new radio brands. The confidence to make those bold commitments was fuelled by an unparalleled boom in commercial radio revenues, and radio’s arrival as a darling of the advertising market. Talk of 6% shares of display advertising abounded, and moving to digital would allow commercial radio to compete against the BBC on terms apparently tilted in its favour.

But the very environment that provided the confidence to start digital was also an environment without fear, and without the imperative for change. Simply owning spectrum and putting out cookie-cutter replicas of analogue radio stations and analogue radio sets met the crude targets of “successful digital”. Without the fear of extinction, evolution was never a high item on the agenda, and ideas to move digital stations to something genuinely plugged into peoples’ digital lives just seemed like unnecessary expense and hassle.

Now the tide has turned, and the radio industry is hurting. As predictions of the threat from on-line began to come true, the money that was needed to fund the evolution of radio simply drained away. Commercial Radio frittered away the rich years by not investing enough in digital product evolution. A vast proportion (95%+) of the money allocated to digital was sucked into appalling infrastructure contracts, which are wholly unwarranted, and do not stand up to close inspection. Those costs became the headlines, and endanger the short-term prospects for the platform. They also took valuable cash away from the product evolution which would ultimately have created new value in radio.

As is often the case, the radio industry now faces having to evolve and re-invent itself at the beginning of a wider economic downturn where money is tight, and pressures to cut costs are enormous. As the time horizons for investment returns get shorter, in part driven by the apparent liquidity that private equity offers, the prospects for evolution are not great.

In the UK at least, the hard times for digital are now. There needs to be a wholesale change in the infrastructure cost of digital to ensure its short-term survival and to put it on a sensible economic footing for the future. If the costs of infrastructure can be realigned to reality, it will remove many of the barriers to genuine new entrants to the market, and to true evolution of the radio product. But once those barriers have been removed, it needs a hearts and minds commitment from the radio industry to create something new, something relevant in today’s media environment that can really exploit the tremendous opportunity that free, mobile, cost-effective, digital broadcast spectrum could bring.

Virgin sticks to the knitting

Elizabeth, Gabrielle and I

Elizabeth, Gabrielle and I by thejulietfiles@ flickr

I don’t think there was much surprise today at the announcement that Virgin Radio Viva will not be launching on the second national multiplex. Certainly far less surprise than there was when it was announced that Virgin was going to launch a station called “Viva” aimed at 30-something females (someone didn’t realise that the name Viva is jinxed).

The justification is that Virgin will focus on guitar driven rock, which makes sense. It’s what listeners understand Virgin to stand for, and why on earth would you want to build the Virgin brand up even more for Richard Branson?

Virgin Radio Groove will also be disappearing, although its carriage on DAB was pretty limited. At least they’ll get some money from auctioning off the EPG slots on Sky.

Viva not appearing is, broadly speaking, good news. DAB didn’t need another service  targeting the eponymous “30-something female”. Clearing that space might allow C4 to do something really interesting that would never have made it through the application stage. It does also highlight the relatively slow-movement of the licensing regime against an increasingly fluid and fast moving radio industry that is beginning to synchronise against Internet time rather than late 1970’s BBC time.

2008 could be a fascinating time for national DAB. C4 could do marvellous things, and DigitalOne (eventually freed from the shackles of BT Movio) could actually compete with new services. I am optomistic that the competition between C4D and D1 will be based not just on new audio services, but on finally making some exciting data services too.

“Does DAB have a point?”

Fridge Top by Kill Pop @ Flickr

Fridge Top by Kill Pop @ flickr (CC)

There’s a BBC kids TV show which includes an animated sequence featuring a blue cow having the most incredulous imaginary adventures. The verbal cue for this segment is for one cow to turn to another and say, in a bored, drawn-out drawl “Oh.. She’s at it again…”.

Anyway, Jack Schofield’s written another article about DAB/DAB+ etc. in the Guardian today. It’s here, although you’ll probably either have seen it already or have a fair idea of what it says.

Basically, Jack’s postulation (and I know you’ll be shocked to hear this) is that there’s no point to DAB Digital Radio. It’s low sound quality, and you can get the same (in his opinion, mediocre) range of channels from Freeview or a WiFi Radio.

Done the sound quality thing. Jack has a gourmet view, the vast majority of people appear to have Tesco/Asda view. There will be quality platforms for audio, but they’ll appeal to, and have to be funded by, the diminishingly small number of people with sufficient passion for it. So I’m not going to reheat that debate again.

But let’s look at Jack’s view on how you’ll get radio, range of choice and quality of content.

I’m bemused that Jack thinks that the absence or presence of DAB will change the quality of radio programming. If quality is an inverse product of quantity, and technologies like broadband, digital satellite, direct satellite, cable, 3G (… continue at your leisure) allow an unending amount of radio stations to be formed and distributed, how would having or not having DAB make a difference? In a way, by establishing a platform that does have some genuine cost to entry there is an investment threshold that needs to be cleared and that generally means having “a plan”. Think back to the early days of satellite TV and how the “quality press” used to lay into the quality of programming then. Don’t journalists learn from the past? Now that digital TV is squarely established as the primary delivery platform, guess what – there’s more quality programming there.

Last point. DAB as a delivery platform. Jack encourages people to buy a WiFi radio or a Freeview box, because that’s a better investment than DAB. Well, don’t expect to pick your Freeview box and move it around the house, or have it on the kitchen windowsill, as it’s going to need one of those big “aerial” things on top of your house to work properly. So if you are going to use Freeview for radio, be sure to carry a length of RG75 coaxial cable round with you, a 8mm drill bit, some cable clips and a tube of waterproof filler for all the holes you’re going to drill in your window frames. And don’t be disappointed if radio is dropped from the Freeview platform to make way for more TV.

WiFi Radios are certainly fine. I have one, in my kitchen. There’s a specific, unusual, reason for that which certainly (and I can prove this statistically if required) puts me in less than 4% of the population. My kitchen WiFi radio is on for 5-10 minutes a day. But WiFi radio is predicated on a future of unlimited, unmetered, internet bandwidth, which certainly isn’t a given. And it requires a certain Quality of Service to operate correctly, which also isn’t guaranteed. If Internet streaming radio ever made anyone serious money, you can bet that the ISPs in the middle would want to find a way of worming their way into the business plan.

Referring back to my representative British Radio Listener, when presented with a choice of over 6,500 radio stations to listen to, what are they going to do? Yes, they’re going to listen to the ones they know. There is a point where increased choice goes beyond what’s viable for people to understand.

It does appear that Jack lives his life within the confines of his home. I wonder how he envisages people listening to radio on the move in the future? Car? Handheld radio? Travelling away from home? Your WiFi radio will work, apparently for free once you’ve paid for your broadband, within the radius of your WiFi router. But no further.

DAB is not the platform for a high quality audiophilic listening experience. DAB is not the platform to provide over 6,500+ channels of radio stations. It’s not positioned to do that, it’s not marketed to do that, so don’t compare it against those expectations and claim it’s a failure.

DAB is the most pragmatic, cost-effective, universally available technology for radio’s digital future. It’s not the only technology – IP, 3G, Satellite etc. will all have their place – but DAB is the best all rounder for the medium that’s all around us.

 [Bootnote] Happy Birthday to DigitalOne, which launched at 11am on the 15th November 1999, and is widely credited with catalysing the growth of DAB Digital Radio in the UK. DAB is still growing in popularity, which might not be said of “Sporty Spice” who performed the switch-on.

Where do Good Ideas come from?

No Msg Zone by Quiet Nights of Gotham @ flickr

No Msg Zone by Quiet Nights of Gotham @ flickr

I’ll have to admit I was both appalled and amused by Mark Ramsey’s latest blog item, “Text Messaging – New Revenue for Radio”. Mark, quite rightly, challenges radio stations to go out and investigate the opportunities that SMS Text Messaging can bring to radio stations, and the revenues it can create.

I’m amused because it’s a very symbolic reminder of how great the chasm is between radio in the US, and radio in pretty much the whole of the rest of the world. I can’t think of a country in Europe, Asia or Australasia where the radio stations aren’t using SMS as a primary component of audience interaction, and raising some revenue as a result. Indeed, so great and enthusiastic has been the engagement of radio and TV broadcasters in the UK to embrace revenue generating SMS activity, that it’s provoked a rather nasty backlash from consumers and regulators. Wouldn’t Mark’s blog have been even more effective if he’d Googled on the subject a bit, and appended a warning along the lines of “hey, but check out what happened in the UK when they tried to push it too far, and learn from them”?

Assuming that SMS has been part of the UK broadcasting landscape since 2001 (and I can say with some authority that the DAB station “Core” in the UK was using SMS as its primary listener contact from 15th November 1999), we’re at least 5-6 years ahead of the US. Come learn from us, but start by understanding that you’re not forging ahead into unknown territory.

When I get the opportunity to talk at conferences or with broadcasters who are at different phases in their development of new technology, I always try and highlight the things we have seen go wrong. Knowing what can go wrong and how to avoid it, in my opinion, at least as valuable as knowing what went right.

What appalled me about Mark’s post is, in fact, not really about Mark’s post. What worries me is the widely held assumption that the US radio industry is leading the global development of radio, and that US commentators are more informed and astute than their European counterparts. Not only does this apply to things like SMS messaging, but also subjects like “Why WiMax is the perfect platform for radio” (wrong…) and in programming areas too – witness the flocking to the “Jack” music format.

I consciously decided not to attend NAB Europe in Barcelona this year after some disappointing and frustrating experiences at the last two events. It’s marvellous to bring speakers from the US over to NAB Europe, but could someone please tell them to adjust their attitudes before engaging mouth? Europe may not speak English, but we’re miles and miles ahead of the US industry, which has got stuck in the turgidity of consolidation and insular thinking. From the feedback I received from colleagues at the event, my decision to stay home and work on other projects  looked to be a good one.

This is not a diatribe against the US radio industry and US commentators. They are where they are, and in a lot of cases their landscape is dramatically different to the one the rest of the world lives in. Europe’s infatuation with PSBs will never be understood outside of Europe (and even those of us who live here do wonder sometimes), and I’ll never understand the popularity of Country and Western as a music format. Celebrate the differences rather than trying to iron them out. If anything, my concern is that people in the industry don’t look outside their comfort zones when looking for innovation and future thinking. There are great things happening in radio in Europe, Asia and Australasia and just because those great things are being done in German, Italian, Swedish, Malay, Chinese, or Thai doesn’t lessen their value to a global radio industry.

Nokia Visual Radio – Redux

Nokia Visual Radio on a handset

 

Installations Folder on N76 by RafeB @ flickr

Nokia Visual Radio had everything going for it, so why hasn’t it taken off?

The premise of adding visual and interactive content to radio has been proven by various research projects, and Nokia showed an outstanding commitment by putting the client software on virtually every one of their mainstream handsets for the last couple of years. Given the normal churn rate of handsets, that must mean that virtually every Nokia phone in mainstream use (and in turn, the majority of handsets in use) has access to the service. That’s millions and millions of consumers in most European countries who could access synchronised visual content from radio stations, and interact. From a commercial point of view, it ought to be an incredibly powerful proposition – direct response to radio/visual advertising from mobile handsets.

So why are there only 3 UK radio stations participating? Why are there less than 20 stations worldwide using the technology?

The biggest single stumbling block has been a comprehensive mis-understanding of the degree of effort radio stations were able (or willing) to put into producing the service. The initial software was so laughably bad, it was actually comical. I know one station that pretty much had three people authoring the output in real-time; that’s not software, that’s a pair of lead-boots. Nokia had advisors with plenty of technology experience, it’s fascinating to see such a disconnect with the real world of radio.

I was really pleased to see this critical bit of the chain fixed recently, with the news that RCS’s excellent (and frankly, visionary) Radioshow software is going to be the authoring tool for radio stations. Or more to the point, it allows radio stations to enter the Visual Radio business by simply piping their “playing now” information from their playout system through to RCS. Hopefully by dramatically lowering the bar, there will be far more stations on the service, creating the critical mass to make it a mainstream success.

There are more things that could be improved with Nokia Visual Radio – it should use RDS to identify a station and start the NVR service, rather than the extremely clunky directory system; and of course, the best way to deliver radio and data services to mobile devices is DAB Digital Radio. But I would say that Nokia have already invested a lot in Nokia Visual Radio, so for the time being it might be good for the radio industry to show some interest in return.

Join the team

Speak and Spell

Circuit Bent Speak and Spell by jamie_hladky @ flickr (CC-BY)

If you’re a radio loving tech geek (here’s hoping I’m understanding at least one of my audience segments), then there’s an opportunity to join the Creative Technology team at GCap Media, based in Central Bristol.

If you’re a relatively accomplished Java (J2EE) developer who knows about things like webservices, RMI, Jini, and can do a bit of light project organisation (definately not full scale project management though), then this might be a good job for. If you love using technology creatively, and love the idea of being involved with early-phase technology development, it might be even more of a job for you. Knowing some PHP/XHTML/CSS, and loving music and radio would top it all off.

Drop me an e-mail if you want the full job info. (I can recommend relocation from London to Bristol, by the way).

WiMax – not radio’s greatest threat

I wasn’t going to follow up on Mark Ramsey’s recently blog post “The Future of Radio Will Be An Experience“, as I thought most of it was bang on the money. However, there was part of it that was bugging me, and a conversation with a colleague in the pub after work on Friday prompted me to respond to one point.

My colleague expressed his concern as “WiMax is going to be a real threat to radio”. Mark postulates the same thing periodically in his blog, and used it as a hook in the posting I’m referring to.

So what did I say to my colleague, admittedly over a couple of pints of Wild Hare, to influence his thinking?

We have a real confusion, in part created by the promoters of new technologies like WiMax, between the “application” and the “bearer”. The application is what the consumer experiences, and the bearer is how they get it. So in this case, the application is “radio” and the bearer is “WiMax”.

I’m very clear that long-term success comes from defining a compelling application. Once you’ve worked out what people will want to use and get excited about, then you work out what bearer is best to get it to them with.

So let me briefly define how I think the application of “traditional mass consumption time-linear radio” will look in the future. Yes, there will be other forms of radio, but this example will expose the issues just as well.

I expect that “radio” will continue to be largely consumed as a simultaneous experience by large numbers of people (10,000 – 100,000+), and it will consist of a selection of audio services accompanied by still visuals, some browseable content and a stream of meta-data describing what’s happening on air. It will be mobile, received on battery-powered handheld devices like MP3 players, and have an astonishingly wide range of devices from £29 (US$60) kitchen radios, home entertainment systems, and continue to be a major part of the in-car entertainment experience. Weekly usage will be almost universal. It will be largely free-to-air and advertising funded.

WiMax is a very interesting technology, assuming that theory and field-tests turn into real-life experiences. It’s designed to be wide-area wireless broadband internet, but to achieve this aim it will need dedicated spectrum. As any user of WiFi devices can tell you, the free-for-all of unlicenced spectrum leads to incredibly unpredictable quality of service, and coverage that changes daily. So WiMax operators, if they are to provide any kind of reliability, will have to purchase dedicated spectrum from government, and that’s not cheap. Ask the mobile phone companies in Europe who coughed up about £20bn (€32bn, US$40bn) for their 3G spectrum. Whatever that spectrum costs, it will have to be shared between the users. Added to that, WiMax base stations will cover relatively small areas (larger than mobile phone basestations, way smaller than traditional radio transmitters) so there will be a lot of them, which increases the cost again. WiMax networks will not be cheap.

So on the surface WiMax works the same way as broadband, and therefore appears to be ideal for “radio”, because “radio” works so well on broadband now. Well, the problem is that it won’t work on broadband. It works now, because so few people, relatively speaking, are using it. I very much doubt that more than 10% of the peak audience of any radio station is through streaming. There has been genuine concern about the effect of applications like Joost and the BBC iPlayer on the general health of the Internet if they become successful. It simply won’t scale indefinately. And if genuine wired broadband won’t scale, WiMax doubly-so.

When demand for capacity outstrips supply, the operators have to start prioritising the capacity, which is called managing the “quality of service”. If your e-mail comes down in spurts, you probably don’t know or mind. If your radio or TV services start buffering and glitching, you get annoyed. So providers of real-time media have much more demanding “quality of service” requirements. The easiest way for the operators to deliver quality of service is to charge the provider a premium to access their network and provide guarantees on delivery. Conversely, anyone who isn’t signed up may find their traffic being shunted down the priority list to a point where it simply doesn’t work some (or most) of the time. It’s a platform lockout.

So if the application is “radio” (as described above), how well does it fix WiMax?

  • The WiMax network would use expensive spectrum and have expensive infrastructure.
  • Every radio would need an ongoing subscription to the WiMax network.
  • Each service would use a proportion of that spectrum and infrastructure, which is finite.
  • The operator may well charge a premium to the service provider for the right quality of service.

So whilst you can, technically, get some degree of radio to work on WiMax, it’ll be considerably more expensive than using a traditional broadcast infrastructure, cost the listener real money for WiMax subscriptions, leave the service providers open to exploitation by the network operators, and make building a £29 kitchen radio almost impossible.

I’m sure some people will believe that “the market will fix these issues” and so on, but these limitations are those imposed by the laws of physics which won’t respond to profit and business planning. If you want wireless wide-area broadband internet, it will be more expensive than the equivalent capacity delivered one-way as broadcast on broadcast infrastructure.

What Mark goes on to describe in his original blog post is a new application of radio which is genuinely threatening. If traditional radio companies can’t create new and interesting applications for radio, then they will get blown out of the water by new entrants. But the emergence of a technology like WiMax simply allows those better ideas to get a foot in the door, and it they become successful, they will end up using broadcast infrastructure because it’s the right bearer for mass-market media experiences.
