Sound film
The primary steps in the commercialization of sound cinema were taken in the mid- to late 1920s. At first, the sound films which included synchronized dialogue, known as "talking pictures", or "talkies", were exclusively shorts. The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie was "The Jazz Singer", released in October 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology. Sound-on-film, however, would soon become the standard for talking pictures.
Phoenix Cinema
In 1924, the cinema's name changed to the 'Coliseum'. In 1925, the cinema was sold to Home Counties Theatres Ltd, which also owned the Athenaeum Picture Playhouse and the Summerland Cinema, both in Muswell Hill. At this time, the typical programme was silent movies accompanied by live music, plus variety acts such as singers, magicians and comedians. But in 1928, British cinema went through a huge transformation when the first sound film, "The Jazz Singer", featuring the voice of the film's star Al Jolson, premiered in the Piccadilly Theatre, London . Cinemas across London started the transition to sound and on 22 July 1929 this cinema was the first in the area to show a sound film, screening Al Jolson's "The Singing Fool".
