O Entertainment is the production company founded by filmmaker Steve Oedekerk, known for co-producing Nickelodeon projects such as The Adventures of Jimmy Neutron, Boy Genius and Barnyard. Its short logo ident closed episodes, which is how many viewers first memorised the jingle from childhood broadcasts. Clips of old production logos later circulated widely on video and soundboard sites, and this sting was kept alive by nostalgia posts, logo collections and editors borrowing the familiar sign-off for parody endings, fake credits sequences and retro television jokes online.
