I don't think they do or at least not in the sense that is portrayed, it might be on in the background but that's about it.
Used to go into the quite plush offices of a busy family owned and run Indian firm in the Wembley area of London. In there they had about 6 tv screens on the wall all blazing away with different things on, mostly business news, general news, stock markets etc.
There was one that often had sport on, all this was just a backdrop as they sat at their desks on their phones, PC's and went about their work.
I reckon it'll be similar with this lot, just background noise.
