"This year the BBC celebrates a century at the forefront of British broadcasting and media. Beginning with radio and then inaugurating the "world's first regular high-definition public TV service" in 1936, the BBC has been a pioneer from its beginnings to today.
These are the shows that revolutionised the broadcasting landscape by defining and developing entire genres; here is the creative talent that broke ground to represent diverse communities across the UK in new and meaningful ways; these are the programmes whose impact changed social attitudes by challenging the status quo; and the technological landmarks that shaped how we watch television today.
This list has been shaped by contributors from across the BFI, who nominated titles for consideration to a core team of BFI curators and programmers, who then honed the list to the 100 programmes below."
