A note, too, about Milton Berle: much of the reason for his
popularity in the '40s and '50s is because he came along when
television was like inventing the wheel: nobody knew yet where
it was going, but compared to the travelogues and cooking shows
that dominated early television, Berle (along with Ed Sullivan, whose
mannerisms were savaged from the very beginning) represented big-time
entertainment to the owners of the earliest sets.
I've seen a few of his early shows, and....meh.

People like to point out the huge ratings Miltie pulled early on, but they forget a few things. One, in his earliest seasons, in many markets he had little to no competition. Unless you were fortunate enough to live in one of the few multi-channel markets, your choices were Uncle Miltie, or the radio. Second, even though early shows were replete with old vaudeville schtick that predated the wheel, it was brand-new to millions of viewers who had never set foot inside a vaudeville theater. Third, TV was so novel that the actual quality and content of the programming was almost incidental -- it was new, and it was exciting to have moving images -- of
anything -- coming right into your living room, where you didn't have to brave the elements, commute, and stand in line for a ticket to see a show -- here it was, free, in your own home, where you could sit in your favorite chair in your bathrobe, stay cool/warm/dry, and be entertained.
