Ask anyone their favorite Nickelodeon show, and they'll probably betray their age. Millennials might mention All That or Drake & Josh, while kids today will likely mention Henry Danger or The Thundermans. Everyone, however, believes in SpongeBob supremacy. Nickelodeon might have changed over the years, but it's still a source of entertainment and comfort for plenty of kids, preteens, and nostalgic adults.
