Kenneth "Ken" Barlow is a fictional character from the British ITV soap opera, "Coronation Street", played by William Roache.
 Ken was created by Tony Warren as one of "Coronation Street's" original characters.
 He debuted in the soap's first episode on 9 December 1960.
 Having appeared continuously since the programme's inception, December 2010 marked Ken's 50th anniversary on-screen.
 At this time, Roache officially became the longest-serving actor in a televised soap opera.
 Roache was honoured at the 2010 Guinness World Records ceremony for the achievement, when he surpassed actor Don Hastings from the American soap opera "As the World Turns", who previously held this title.
 Roache stated in 2010 that he has no plans to leave the role and will remain in "Coronation Street" for as long as they will have him.
"The Road to Coronation Street" was written by Daran Little, a long-time archivist on "Coronation Street" who became a scriptwriter.
 At the time, however, Little was a scriptwriter for "Coronation Street"' s rival, "EastEnders", broadcast on BBC One.
 Though "Coronation Street" is, and always has been, broadcast on ITV, a competing network, the idea of documenting the show on the anniversary of its half century running was picked up by its natural rival, the BBC.
 It has, however, been repeated several times on ITV3 and, on the occasion of Tony Warren's death, ITV.
