Knox also contributed to the one-off ITV documentary "Coronation Street: A Moving Story", which saw the transition from recording at Granada Studios to the new MediaCityUK in 2014. On 31 December 2014, ITV celebrated Knox's contribution to "Coronation Street" with a special 60-minute documentary for her 50 years as Rita, called "Rita and Me". In December 2017, she gave an Interview on ITV's "Lorraine". Since the departure of Eileen Derbyshire, who played Emily Bishop from January 1961 to January 2016, Knox is the second-longest serving cast member behind William Roache, who has played Ken Barlow since the first episode in December 1960.
