Sky Sports 4 (originally launched as Sky Sports Xtra) is the fourth Sports channel launched by Sky. It airs repeats and live events of many Sky Sports programmes, such as La Liga. The channel launched in April 1999, and is a free bonus channel for those who subscribe to both Sky Sports 1 and Sky Sports 2. The name Xtra rather than Sky Sports 4 was chosen as the original intention of the channel was to simulcast sporting events showing on the main channels with the addition of interactive services.The channel has stopped simulcasting, and the interactive services have moved to the main Sky Sports channels. Sky Sports 4 now shows live and recorded sports events, and is in effect a fourth main Sky Sports channel. In light of this, on 6 January 2010, Sky Sports Xtra was renamed Sky Sports 4.
