In addition to the first run rights for the rest of the series made to date, Sky 1 also acquired rerun rights to the episodes previously shown by the BBC and a TV movie version of "Unification I" , which was shown on an exclusive "movie" channel rather than as part of the main run of the series. Sky also bought the first run rights for Star Trek: Deep Space Nine, Star Trek: Voyager, and Star Trek: Enterprise. Deep Space Nine's sixth season aired on Sky 1 from 19 October 1998 to 12 April 1999 .
