CORONATION STREET (1960)

FOR a show which began life with a trial run of just 13 episodes, this not-so-grim-up-north soap hasn’t done too badly. Within a few months of its debut it was the most-watched programme on telly and it is now the world’s longest-running TV soap. The 50th anniversary episode, filmed live, featured a devastating tram crash. Another live show marked ITV’s 60th birthday last year. Creator Tony Warren died in March.
