ORLANDO, Fla. (AP) _ Nickelodeon Studios taped its 1,000th program Wednesday for its television network for young people.

Nickelodeon Studios has produced more than 285 episodes of its various shows each year since it opened June 7, 1990, at Universal Studios Florida in Orlando, said General Manager Scott Davis. Programs were previously recorded in New York and Los Angeles.

It has become the largest studio in the world dedicated to children's television. Productions range from messy game shows such as ''Family Double Dare'' to sitcoms such as ''Clarissa Explains it All,'' the network's most popular show.

Nickelodeon employs about 300 people in an average week, including writers, production managers, artists, designers and technicians.

The Nickelodeon channel is available on cable television.
