Bochco died Sunday morning at home, surrounded by family, according to Phillip Arnold, Bochco's personal assistant.
Bochco received a transplant in 2014 which helped prolong his life. It would go on to win 26 of them, and led Bochco on a course to earn several Peabody awards in addition to his 10 Emmys.
"All of us who grew up watching great TV and have benefited from the ground he broke owe pioneer Steven Bochco a debt of gratitude", he added.
Born in NY, his father, Rudolph, was a violinist and his mother, Mimi, was a painter and jewelry designer.
Bosson met Bochco while studying at Carnegie Mellon University in Pittsburgh, Pennsylvania. He was 74 years old.
Due to his success, Steven signed a milestone deal with ABC to produce 10 television series, The Guardian reported.
"It was one among the many lessons I learned from Grant, and always tried to emulate: Protect your talent".
Bochco started as a TV writer in the 1960s, working on such shows as "Columbo". "If I can't do that, I'll kill it for the next person who comes down the road".
The mentor and the mentee teamed to create together the series Doogie Howser, M.D., which ran from 1989-93 and made Neil Patrick Harris a star.
Airing at 10 p.m., "NYPD Blue" offered a glimpse of the occasional bare bottom and saltier language than was usually heard on TV. "We were certainly aware of advancing the agenda".
From actor Ken Olin: "I was 28, married, & the father of a baby boy when the creator of "Hill St. Blues" came to NYC to cast a show about minor league baseball". They probably wouldn't exist without the realistic grit and sprawling ensembles established in Hill Street Blues, which would receive 98 Emmy nominations over its seven-season run, or L.A. Law and NYPD Blue.
He is survived by his third wife, Dayna Kalins, his children Melissa Bochco, Jesse Bochco and Sean Flanagan, and two grandchildren.
