Andy Pandy first aired on Tuesday 11 July 1950 and became very popular straight away. Further episodes followed and were soon heavily repeated, rounding off programmes for housewives and mothers every Tuesday (and on Thursdays from Summer 1952).

The programme became the cornerstone of the Watch With Mother strand which began in 1953. Made on film rather than broadcast live, surviving episodes are therefore now among the earliest relics of British television history.

In each episode, the narrator spoke directly to both the audience and Andy, mediating between them: 'Andy Pandy, the children are here' or 'we must sing something for the children first'. Andy and the friends who later joined him, Teddy and the rag doll Looby Loo (who only came to life when Andy and Teddy weren't around), were mute throughout.

Episodes were a collection of unrelated songs and games with no ongoing narrative. Viewers were invited to sing or dance along with what was going on on-screen. Each episode ended with a variation on the famous song: "Time to go home / Time to go home / Andy is waving goodbye."

The original black and white episodes - perhaps fewer than forty in total are thought to have been made up until 1959. Shown weekly in an almost unbroken run until 1969, the film prints eventually became too damaged to broadcast so Westerham produced another thirteen episodes in 1970, now in colour but otherwise virtually unchanged. These would be shown right through the 70s.

In March 2002 Andy, minus his strings, returned to entertain yet another generation of children world-wide, as a modern stop motion series made by Cosgrove Hall.
