BBC Two had been launched in 1964, but had struggled to capture the public's imagination. When Attenborough arrived as controller, he quickly abolished the channel's quirky kangaroo mascot and shook up the schedule. With a mission to make BBC Two's output diverse and different from that offered by other networks, he began to establish a portfolio of programmes that defined the channel's identity for decades to come. Under his tenure, music, the arts, entertainment, archaeology, experimental comedy, travel, drama, sport, business, science and natural history all found a place in the weekly schedules. Often, an eclectic mix was offered within a single evening's viewing. Programmes he commissioned included Man Alive, Call My Bluff, Chronicle, Match of the Day, The Old Grey Whistle Test, Monty Python's Flying Circus and The Money Programme. With the addition of colour television, Attenborough brought snooker to the BBC to show the benefits of the format, as the sport uses coloured balls. The show - Pot Black was later credited with the boom of the sport into the 1980s.
