hardly. It was a another cop show, not the first. And twenty years later the Sopranos? long pregnancy.
OTOH: Two words Vampire Shows, the new genre of the 21st Century
And "It was a serialized mixture of drama and comedy featuring diverse, colorful and three-dimensional characters "
Buffy the Vampire Slayer
Also No Buffy, no Angel, No Summer Glau
I agree with the comments about Breaking Bad etc. I loved Hill Street, but influential?
I would say All In the Family and The Tonight Show with Carson. For better or worse.
