John Stevenson (born 1937) is one of the most prolific writers in the history of Coronation Street. Working on the programme between from May 1976 to May 2000 (when he left the programme following a dispute with producer Jane Macnaught), and again from April 2002 to 2006 - by the end of 2002 he had written 399 episodes. He co-created 1980s comedy drama Brass with fellow Street writer Julian Roach, and has penned episodes of Heartbeat, Oh, Doctor Beeching! and The Grimleys.
Stevenson was the northern theatre critic and showbusiness writer for The Daily Mail and wrote his first ever script in 1968 at the behest of Peter Eckersley for a piloted comedy series called Her Majesty's Pleasure (created by Leslie Duxbury). He met Bill Podmore the same year and worked for him on many series such as Nearest and Dearest. Podmore, more than most, appreciated the importance of writers in television, and quickly recruited Stevenson when he became the Street 's producer in 1976. He also scripted the sitcom, Mother's Ruin, starring Coronation Street actor, Roy Barraclough.
