Tiscali TV is often overlooked, mainly due to the large amount of mainstream advertising BT has given its own competing product BT Vision.
Tiscali TV differs from the BT Vision offering, in that it delivers live TV shows and films over the ADSL connection, and has added Tiscali+ PVR which means that Freeview channels are also available. Tiscali TV has its roots in the original HomeChoice service that launched back in 2000 using a 2.3Mbps ADSL connection offering pause and rewind facilities well before Virgin Media and Sky.
ISPreview has noted that in March 2008 Tiscali set a target of 200,000 customers, but according to the latest figures from Ofcom in Q4 2008 they were still around the 100,000 mark.
The downside of any of this and BT Vision is that it requires your telephone line to be short enough to reliably support download speeds of over 2Mbps to watch the IPTV content. Something like 80 to 90% of telephone lines should support the speeds necessary.
Update Thursday 9am: We slipped up on the calendar and did not notice the original item was centered around a March 2008 article on Digital Spy, thanks to Mark Jackson at ISPreview for pointing us in the right direction.
