Coronation Street is a British soap opera, initially produced by Granada Television. Created by writer Tony Warren, Coronation Street first broadcast on ITV on 9 December 1960. The following is a list of characters introduced in the show's fifth year, by order of first appearance. In what remains one of the serial's most dramatic and influential years to date, 1964 saw no less than four producers take the helm of the show. Apart from a short month-long break in which original producer Stuart Latham took over for one last stint, Margaret Morris presided over Coronation Street until May, in which she introduced Irma Ogden (Sandra Gough) in late January. Radical young producer Tim Aspinall took the reins in May and quickly made his mark by writing out several characters including Frank Barlow, Harry and Concepta Hewitt, Jerry and Myra Booth and most controversially, Martha Longhurst, a favourite with viewers who Aspinall chose to kill off in his first episode. A week later, Aspinall introduced a new regular in the form of Charlie Moffitt (Gordon Rollings). In June, Aspinall chose to give newcomer Irma Ogden a family, and cast Bernard Youens and Jean Alexander in the roles of Irma's parents Stan and Hilda. The couple proved popular and remained with the series for over twenty years. Today, Hilda Ogden is widely regarded as the greatest and most iconic character in Coronation Street's long, illustrious history. After a short, turbulent stint, Aspinall departed the show in September and H.V. Kershaw returned to the role. Kershaw introduced Sandra Petty (Heather Moore) in October, originally in a guest role. Barbara Mullaney also made her first appearance as Rita Littlewood for a single episode in December, eight years before returning as a regular cast member.
