First, while technically used in the movie first, there was the Saturday morning cartoon, The Pink Panther Show, which premiered in 1969. Henry Mancini's swingin' theme:
The theme song to Mannix, by Lalo Schifrin is another tune I should have included. When I was around 8 or 9 years old (possibly younger), I was "playing Mannix" in my neighborhood, armed with a cap gun, while loudly humming the theme song to myself. An older boy from across the street overheard me doing so, and he teased me incessantly about it. I remember this like it was yesterday.
And just one more, a show I watched in rerun form every day for a while during the early '70s, The Odd Couple, had a really cool, and yes, jazzy, theme song. And what do you know? It was composed by Neil Hefti, the arranger of one my favorite Sinatra albums, Sinatra and Swingin' Brass.
Well there you have it, my case for how m-m-m-my g-g-generation and I were pre-programmed to quite possibly enjoy jazz music when we became old and gray. I guess it could have been worse - "they" could have done a Manchurian candidate kind of thing to us.....Now I must play solitaire.
