UK Horizons was one of the original three UKTV network channels, launching on 1 November 1997. The channel focused on airing documentaries and other factual programmes and was named after BBC’s Horizon programme, which itself formed a staple of its output in the early years. It also produced extended versions of top BBC brands such as Top Gear and Tomorrow’s World. The channel closed on 7 March 2004, as part of UKTV’s relaunch. UK Horizons was split into two new channels – UKTV Documentary and UKTV People, which both launched the following day on 8 March. UKTV Documentary took over UK Horizons’ slot, as well as the UK Horizons +1 timeshift service, with UKTV People being the “new” channel.
