From wholesome sitcoms to Western adventures, the best '50s TV shows highlight the first real decade of television popularity.

Bonanza's first season began in the fall of 1959.

It's a '60s series, and in fact there were a few early '70s seasons as well. Definitely not a 1950s series.

No Jack Benny Program or Burns and Allen, at least they had Alfred Hitchcock Presents at #3. A site that mainly features more recent shows probably hasn't heard of Bachelor Father. John Forsythe starred in that underrated gem a few decades before Dynasty.
