 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.
