The character of John Munch, as portrayed by Belzer, began in 1993 on NBC's Homicide: Life on the Street, set in Baltimore.

In 1999, Homicide had a crossover with Law & Order. Later in that same year, Munch then joined Law & Order: Special Victims, as a regular character.

In the end, Belzer, as Munch, appeared on NBC's Homicide, Law & Order, Law & Order: SVU, Law & Order: Trial by Jury and 30 Rock. He also appeared (again, as Munch) in Fox's Arrested Development and The X-Files; UPN's The Beat; HBO's The Wire; NetFlix's Unbreakable Kimmy Schmidt; and finally, on ABC's Jimmy Kimmel Live.
