Television documentaries started on BBC television, with the long-running series Look, a studio-based magazine progamme with filmed inserts, hosted by Sir Peter Scott. The first 50-minute weekly documentary series was The World About Us, which began with a colour installment from the French film-maker Haroun Tazieff, called "Volcano". Around 1982, the series changed its title to The Natural World and is still in production today at the BBC Natural History Unit in Bristol. During the late 1970s and early 1980s several other television companies round the world set up their own specialised natural history departments, including ABC in Melbourne, Australia and TVNZ's unit in Dunedin, New Zealand — both still in existence, the latter having changed its name to NHNZ. ITV's contribution to the genre was Survival, a prolific series of single films. It was eventually axed when the network introduced a controversial new schedule which many commentators have criticised as 'dumbing down'.
