For three consecutive years in the early 1990s, Sky Movies carried several non-film premium content includes World Wrestling Federation's special matches, various music concerts and live boxing competitions (such as the first event was Mike Tyson vs. Buster Douglas on 11 February 1990). This was because at this time all of Sky's other channels, including Sky Sports, were shown free-to-air and during this period, the channel was often referred to as Sky Movies Plus. When Sky Sports became a pay channel on 1 September 1992, Sky Movies stopped showing non-movie related programming.
