Like everybody else on this forum, I love sitcoms. However, in a hundred years time, when we're all dead and buried, will anybody still watch any of the shows we discuss here? Are even the best examples of the art - Fawtly Towers, The Office, Peep Show - doomed to be forgotten? Or, at best, only discussed in universities as part of academic courses looking at late twentieth century/early twenty-first century pop culture?
I think they probably will. Sitcoms don't seem to have the longevity of other art forms, such as plays or novels. Even hugely well regarded and popular shows of just a few decades seem forgotten about now.
