I believe I have discovered the main reason that during the 1950s, "I Love Lucy", "The Honeymooners" and to a lesser extent "The Phil Silvers Show - aka - "You'll Never Get Rich" were the sitcoms of note, and the ones that have stood the test of time better then the many other shows that were on the TV landscape during that decade. They were laugh out loud funny, whereas many of the other shows were mild in comparison. Those other shows had few riotous laugh out loud moments, replaced instead by pleasant "snickers". So credit goes to the writers and actors. I remember my father saying that someone told him "You gotta watch Jackie Gleason's "Honeymooners". My dad put it on, and it instantly became appointment television. Shows like "I Love Lucy" also had more energy. My favorite 1950s sitcom is "Topper", yet I notice how low key it is and I often leave an episode thinking..."they could have made it funnier".
Other shows that are up there in the laughs department were "Amos and Andy" and "The Burns and Allen Show", although to me, Burns and Allen suffered a little in the energy department. I haven't seen enough episodes of "I Married Joan", but that may be a contender too.
