“Steve was a friend and a colleague starting with the first episode of Columbo in 1971 that he wrote and I directed,” said Steven Spielberg. “We have supported and inspired each other ever since and through many deep mutual friendships we have stayed connected for 47 years.  I will miss Steve terribly.

“A devastating loss. For television,” David E. Kelley said about the death of Bochco. “For those who loved him and were loved by him. My beacon, my friend. The ground feels different now.”
