There are in fact 5 irish TV stations, RTE1 & RTE2 (our version of yer BBC), TV3 & there smaller sister station 3e (our version of yer ITV) and our fifth channel is an irish language station called TG4, it is an irish speaking dedicated station but since it has such a small audience, it also shows some US hows like True Blood, the Wire, Nip/Tuck etc.
They are our standard channels (ecept for 3e, that can only be gotten through digital services).
On top of these channels, we can get all the 'Sky' channels that ye get though Sky or NTL/Chorus or whatever. that includes BBC, ITV, sky sports, sky movies... all the channels ye can get, (including UTV) and BBC Northern Ireland).
The most famous Irish TV show is called the Late Late show, its a three hour talk show on everyday friday night and it is the longest running chat show in the world. It has held, and remains to have, extreme cultural and socail importance in ireland. It holds such reverence in Irish culture that the likes of Johnaton Ross, Parkinson or any of the USA chatshows such as Letterman or Leno could only dream of! However i wouldnt advise youtubing that as well, the show is like 40+ years old so theres probaly a lot of clips, from muhammed ali to bono to pat the baker!
If you like Fr. Ted and if you like sports, i would advise checking these videos out. Irish football sport commentary is very different to Linker and co at the BBC and Sky. They analysis the matches a lot more intelligently and critically than their British conterparts.
The first link here is a clip of the normal commentators, while the other ones are from a sketch chow taking the piss out of them all!

Edit: Fr. Ted was indeed made by channel 4 so is technical a British show, even though all the actors, writers and producers were irish themselves. However, RTE (the irish station) never 'turned down' Fr. Ted., Everybody seems to think that but in fact it was never offered to RTE!
