Syfy (formerly known as the Sci Fi Channel), was the original syndicated cable network which showed Star Trek: The Original Series and Star Trek: The Animated Series. The US network was originally owned by Paramount Pictures until its purchase in 2002 by Universal.
On 16 March 2009, Sci Fi announced that it would be renaming itself Syfy in order to end confusion on how to capitalize and stylize "Sci Fi," as well as part of an on-going rebranding effort. The name change became official on 7 July 2009.
TAS aired on the network's animation block until it ended in 1996. TOS aired on Sci Fi until 2004, when G4 and TV Land took the rights from them. In 2007, Sci Fi acquired the rights to the most recent Star Trek series, Enterprise, which began airing on 8 January 2007.
In May 2008, as part of a deal with CBS Paramount Network Television related to the acquisition of broadcast rights to the TV series Ghost Whisperer, Sci Fi acquired broadcast rights to Star Trek: The Next Generation, which had never aired on Sci Fi before. TNG began airing on Sci-Fi on Mondays at 7PM EST on 2 June 2008.   However, the deal was short lived as SyFy lost the rights to TNG at the end of August 2009 so that the series could return to syndicated broadcast television. They regained the rights and shown all-day marathons of TNG on Tuesdays until June 29, 2010.
