In March 1997 the BBC launched one of the most successful children's TV programmes ever. Teletubbies was aimed at toddlers and became controversial for its use of playful language - the BBC fielded complaints from parents who feared that the 'gibberish' language used would stop their children from learning how to speak properly.
