I do agree with your hypothesis, though. It makes sense to prefer the shows that you watched during your formative years.
They didn’t have TV shows during my formative years, I was born in 1930. I liked radio shows like; I Love A Mystery, The Shadow Knows, Terry And the Pirates, The Lone Ranger, Red Ryder, Major Bowes Amateur Hour. Dr IQ...there were more. ;)
I have many, many black and white movies on DVD’s and many new and newer ones.
As for TV shows, I liked Maverick, Have Gun Will Travel, Magnum PI, NYPD, Firefly, Babylon 5, JAG, 24, The Unit.
Today I like Burn Notice, Human Shield, V, Bones, In Plain Sight, Chuck, Justified, White Collar, all motor sports racing on SpeedTV, news on FNC and FBN, also MLB Channel and the NFL Channel.
I don’t like Pro Basketball, Ice Hockey or Soccer, do like Rugby. Don’t like any TV show with a laugh track.
Well, that’s about it for this old curmudgeon, I’ve forgotten much of the past, did some real hard living over the first half of my life... >:-}
