I was just checking Russel's Blog, and I found this post about very interesting. Russel is basically proposing that video and music sites should propose a *.tv version specifically tailored for a navigation on our big TV flat screens as they sometime do for mobile devices.
This makes perfect sense. Traditional sites are often a pain in the ass to navigate on a TV. Not easy to use a mouse where you're in the couch. That's why Free (a french ISP) is proposing its "TeleSites" which are basically a set of HTML coding guidelines and a few XHTML extensi enabling navigation through the remote control and media controls.
This discussion can also be extended to music sites. A few weeks ago I was at a Barbecue at a friend's house, he was using a laptop pluged on its 22 inches TV with Deezer (a French legal music streaming service). I remember to have thought that such an interface should propose full screen ads instead of the traditional Web ads that you clearly don't look at when you're having a beer with the friends in the living room.
In my first startup, Wokup, we designed a rendering technology enabling mobile rendering of Web sites, this is exactly the same kind of technology which is needed for these kind of apps. If I was looking at new business opportunities, I would definitely be trying to inspect how people browsing habits are changing : how they do discover content, how the consume it and how the socialize around it when they are not on their laptop.
