My son has just advised me that Sky have a range of extra channels dedicated to the Olympics. What a waste of money. I am about to phone them up and tell them I am cancelling my susbscription - I have been meaning to do this for a while but this seems like the ideal occasion to do so and to express my contempt and disgust.
The BBC have 24 SD and 24 HD channels dedicated to the Olympics, in addition to BBC1 & 2.
These are available via Virgin Media, Sky, and FreeSat, with a couple available on Freeview HD.
