As of 2018 which TV sitcom holds the record for the Longest Running Sitcom in the World?

I used to skive off school to watch them filming

Ce5 Friend, this series began 4/1/73 (the date quoted here) long b4 1986. my mother watched it (not repeats) and she died in 82. so you're wrong I'm afraid

The final episode was shown in 2010 so why does the question ask “as of 2018”?

P.C Walsh (Louis Emerick) is my relation. appeared in 55 episodes. Y.N.W.A.    JFT96

Tincantitan1, you are so correct
