Drama and entertainment output was studio-based and followed the tradition of live theatre and radio drama; if a radio drama needed to be broadcast at a later date, it was not uncommon to simple reassemble performers and recreate the show. Conventional filmmaking was only gradually introduced from the 1960s. "The Sunday Night Play" (a major event in the 1950s) was performed live in the studio. On Thursday, because telerecording was of insufficient broadcast quality, another live performance followed, the artists returning to perform the play again.
