The MLP fandom is a weird one, as people found it strange to have grown men obsessed with ponies. It has grown largely since its first release and one of the most famous and popular cartoon shows.

Trivia

 * The group name "Mane 6" is a play on the word "Main", combined with 6. This indicates the six main characters. Many other things in the series are puns of things in the real world, like how Manehattan is a play on Manhattan but changed to the former since most ponies know nothing of our kind.
 * There are many references to other media in the show, like how there's a pop star named Coloratura who is nicknamed Rara, a reference to Lady Gaga. Other references includes a time traveling pony named Dr. Whooves, a reference to Dr. Who from the sci-fi series with the same name.
