As of 2021, he is the longest serving, living television actor in a continuous role in the whole world. He is the longest serving soap actor in the world ever, acting and appearing in the same role uninterruptedly since the first episode of the British soap opera Coronation Street (1960) was made and broadcast in 1960. Appeared and/or credited in an average of 25 episodes per year of the soap for 60 years.
