Extra programmes from the US-based FX and Fuel TV channels will be added to the CinemaNow website in July.
The legal downloading of such material has taken off in the past year, with hit shows such as Desperate Housewives and CSI also on sale over the internet.
US networks ABC and CBS have placed episodes from these series on the US version of the iTunes online music store, at a cost of $1.99 (£1.08) each.
Once downloaded, they can be viewed on computers or on portable players.
CinemaNow has also recently reached agreements with Warner Brothers for its films and TV shows, and Disney for its movies. Thanks news.bbc.co.uk |
