Sky Sci-Fi

It was launched in 1995 as a localised variant of the US channel Sci Fi Channel (now Syfy), with a similar programming line-up. It was on air each day from 8:00 am until 2:00 am, but only on cable as a lack of transponder space on satellite meant that it was only able to broadcast for few hours each day on that platform. It wasn't until the launch of Sky Digital in 1998 that the channel's full broadcast hours were available on satellite. Programming in the channel's early years followed the US channel's model, then consisting largely of archive shows such as Lost in Space, The Incredible Hulk, Buck Rogers in the 25th Century, and films from the Paramount and MCA vaults. The channel was also notable for being one of the first UK television channels to show anime movies and television series on a regular basis. These programming choices were supplemented by a few 1980s animated series shown in the mornings such as Robotech, Bionic Six and G-Force, although they were dropped as the channel's lineup became more independent of the original US channel. Currently, most archive and anime programming have been phased out of the channel, which now concentrates on contemporary show, movies, and other programming. One original UK production was the late-night show Headf**k, which featured excerpts from unusual TV shows, short films (including Chris Barfoot 'Phoenix' and 'The Reckoning') and music videos from around the world. Later episodes were presented by David Icke. Programmes on the channel throughout more recent times have included UK premieres of big name US shows like Heroes, Flash Gordon, Eureka, and more recently Knight Rider, Legend of the Seeker and Joss Whedon's Dollhouse. Also shown as of February 2007 are digitally remastered episodes of Star Trek (not to be confused with the remastered series with new CGI); in October the channel secured an exclusive deal with CBS to air Star Trek: The Next Generation episodes, remastered from original film elements to current HD standards with new HD CGI sequences, and as of November 2012 have been broadcasting them in (mostly) chronological order. ==Programming==

As of April 2008, the channel reached an average of three million UK and Ireland households a week, appealing equally to male and female demographics. Initially, the channel shared its analogue satellite transponder with no less than five other channels, limiting its output to early evenings and late nights with the rest of its continuous daytime programming (including cartoons) restricted to cable customers. With the launch of Sky Digital in the UK the channel eventually expanded to exclusive broadcasting on its own channel and now broadcasts round the clock most days each week. ==Most watched programmes==
