Cover for Alan Sepinwall's book "The Revolution Was Televised."

According to HitFix.com TV critic Alan Sepinwall, we're currently living in a golden era of television. 

His new book is called "The Revolution Was Televised: The Cops, Crooks, Slingers and Slayers Who Changed TV Drama Forever," describes how a dozen high-profile dramas from "The Wire" to "Breaking Bad" have redefined the way television is used to tell stories.

These shows broke the mold of traditional one-hour drama by extending storylines over entire seasons. They also introduced us to morally ambiguous characters: a gangster in therapy, a teacher-turned meth dealer.
