Stars and programme-makers look back at the early years of BBC Two in a programme first transmitted in 2004 to commemorate the channel's 40th birthday. After a disastrous power failure on the opening night, long-running series including Playschool and Match of the Day made their debuts and the channel became the first in the UK to broadcast in colour, with groundbreaking programmes including Kenneth Clark's documentary series Civilisation and the adaptation of Robert Graves's I, Claudius. Other series shown on the channel in its first decade include The Likely Lads, The Forsyth Saga, Pot Black, The Goodies and The Old Grey Whistle Test.
