How many Barneys have there been?

There have been several iterations of Barney the Dinosaur, primarily the character from the children's television show "Barney & Friends," which debuted in 1992. The original Barney puppet was created by David Voss and later performed by Bob West. Over the years, the show has featured various costumes and performers, but the character itself has remained consistent as a friendly, purple dinosaur. In addition to the main character, there have been spin-off versions and adaptations, but they all revolve around the same core concept of the lovable dinosaur.
