Fan Service

Fan Service or fanservice is when the creators of a franchise decide to actively cater to their fanbase by doing things that please them, such as by acknowledging a meme the Internet created. Fan Service is an easy way to Please The Audience as it's a way to show that you're paying attention to them and enjoying their fandom of your work.

Even though Fan Service has its upsides, too much of it can leave fans with a feeling of discontent with the content. Making decisions like having the Fan Service Doll make more appearances than usual might have hard-to-satisfy fans call the creators out for taking advantage of the other portion of the fanbase or deriving from the original purpose of the franchise (like telling a story) to make it easier to win fans over by forcing the Fan Favorite wherever possible.
