This is sad and strange maybe...I'm glad his time on Breaking Bad reignited his career.
The first thing I ever saw him in was Homicide: Life on the Street. Looking at IMDB it says he was only in 22 episodes near the end of the show's run. Thinking back it's always seemed like his character started on the show long before that since he played a main character's son.
Before 'Breaking Bad,' Giancarlo Esposito considered arranging his own murder for insurance money
