Claster Television, Inc. was a Baltimore, Maryland–based television distributor founded in 1953 by Bert and Nancy Claster as Romper Room Inc. It was originally a producer of the children's show Romper Room. Romper Room was one of the first pre-schoolchildren's programs, predating Mister Rogers' Neighborhood, Sesame Street, and Barney & Friends. All of Claster's shows ended in 2000, when Hasbro formed a central media division which merged Claster with other Hasbro media and some shows from Claster Television would be owned by Hasbro.
