In 1968 ABC had several shows that would long be remembered but even more that are forgotten. I certainly don’t remember watching many of them. Some were iconic (Big Valley, Peyton Place, etc.) but so many were short lived.
But… I love the music. 1960’s TV had many great theme songs, much more interesting music than what was used decades later. Too much of the ‘80’s and ‘90’s TV shows used very generic sounding pop-music genre.
