I don't know how long this ad has been on TV but I've only started seeing it the last few days. It's a T-Mobile UK advert, apparently they're not a big player in the UK yet and are trying to get the brand name out there and I certainly think this is one way of doing it. They filmed 300 dancers breaking into dance in London's Liverpool Street station and filmed people's reactions as well. Naturally, most of these reactions involved people whipping out their phones and either recording or calling/texting people about what was happening. I really like the advert myself and being a real musical freak, if people suddenly started doing a synchronised dance around me, I'd be enraptured. It'd be like living the dream! And yes, I would take out my phone and start texting everyone I knew about it.
