Just to follow up on some of the posts here.
The
BBC don't collect the Licence Fee, the
TV Licence Authority does. The BBC are run by
Royal Charter, which basically means they're granted licence to broadcast by the government, but they are an independent public corporation.
Besides the BBC, there is also
ITV,
Channel 4 and
Five.
ITV and Five are both commercial companies.
Channel 4 is publicly owned, not for profit. They have a government
remit to push the boundaries, and offer an alternative point of view. They're also only a publishing broadcaster, they cannot producer their own shows, they have to buy a 100% of their output from the independent sector.
Sky are the major pay TV offering, but there are others.
BT and
Tiscalli (and soon Orange too) offer a digital terrestrial/IPTV vod service. Virgin Media offer cable.
There are 2 free to view multichannel offerings too, Freeview and Freesat.
Freeview transmits over the air, and had around 46 channels. Plus some radio channels, and a pay TV service, which downloads shows to your PVR over night, and works like video on demand.
Freesat has around 76 channels including 2 HD services, at the minute, which they're hoping to increase to around 200 by the end of the year.
Pretty much every channel but the BBC has commercials on them.
