In the past few weeks, Twitter has crossed over to our living room and is now a part of our TV viewing experience, primarily for Dragons Den. The Irish version of Dragons Den is mediocre in my opinion, but the fun part is when you combine it with the ‘back chat’ on #ddire. For an explanation of how these ‘hashtags’ work on Twitter, see here.
(apologies for the poor picture, but you get the idea 
In the picture above, Twitter is running on my media PC box (which I built a few months back) and our TV supports PIP, so that’s a mini-screen Dragons Den with various peoples ‘tweets’ about whats happening in the show in the background.
Dragons Den is the only show at the moment that I watch like this, have tried following twitter groups while sporting matches are on (for example, George Hook live tweeted during last weeks Ireland/Scotland rugby match) but personally I find I’m a bit too engaged in the match and the tweets are too much of a distraction (although I do scan them at half time). I’ve also heard that people live tweet during the Late Late Show, but I’m sorry, no amount of amusing Twitter comments would make me sit though that
I know there are many ways of following Twitter whilst watching TV (i.e. laptop, mobile, etc) but I think it would be really great if it was integrated directly into the TV itself. You could optionally have tweets relating to the show your watching scrolling across the bottom of your TV screen (like a stockticker), or superimposed like you can do with teletext – all controllable from your remote.
