Liverpool fans probably didn't feel the need to boo the manager or demand the removal of the board for near enough 40 years. Once we declined (early 90s), the game had moved into the arena where it was more demanding of success to be delivered within 12 months or patience ended. That said, I think Liverpool fans sort of accepted that we had had a bloody good run and it was inevitable that there'd be some fallow years. And the emergence of the internet, 24 hour rolling sports coverage and these big phone-ins means that everyone's opinion gets heard. And the media want to encourage the most extreme opinions as they think that's what constitutes news. Vicious circle innit.
