Periphery Demographic: One of the few cyclic examples. The site started out intended for college dorm students who weren't allowed to keep real pets. Then in the 2001-2003 era, it began to become popular with young children, and the site shifted its focus. Cue 2012, when the old fans are starting to come back, now as college students, and bringing new fans their age with them. Then, in March 2014, the site was bought by the Jump Start company due to their interest in the audience, and thus the Periphery Demographic has now officially become the Primary Demographic once again.
Snarkie: "Jumpstart was interested in Neopets because the audience was older. ;)"
