The Comic Strip Presents... came before The Young Ones but The Young Ones had the greater impact I agree but that was down to the respective audiences of Ch4 / BBC and the CSP was aired on CH4's opening night. But anyway.... my point was, it wasn't the Young Ones that signalled the end of the turgid 60s and 70s formulaic sitcoms, it was the new channel - Ch4, they dragged the BBC in particular into the new era. Ch4 when it started was an absolute breath of fresh air, it ripped up the TV scheduling conventions, it did things other channels wouldn't have dared to, some of it worked, some of it was awful but it isn't an understatement to say that Ch4 revolutionised UK TV and especially the sitcom / comedy fields. A lot of that early Ch4 output was also down to The Comic Strip and it's members (Who were indeed the cast of The Young Ones)
