Free! (Free! - Iwatobi Swim Club) is a sports anime by Kyoto Animation surrounding the lives of High School swimmers. It premiered on July 3, 2013 and it is based on High☆Speed!, a novel by Kouji Ouji. The show follows a group of four male swimmers, all in high school, who start a competitive swim club at their high-school.
The first season of the show started on July 4, 2013, and had a twelve episode run, ending on September 26. A second season, dubbed Eternal Summer! was later confirmed and aired on July 2, 2014, completing the series in September.
The show also has several extras/side stories, light novels, and a prequel film titled High Speed! -Free! Starting Days-' which aired on December 5, 2015.
The fandom for Free! sprung up literally overnight. A commercial by Kyoto Animation aired during episode 10 of Tamako Market in March of 2013, and had spawned a fanbase on Tumblr, Pixiv and elsewhere within 48 hours of its release, due to the shirtless Bishōnen featured in it.  The show was quickly dubbed "Swimming Anime" before its actual name was revealed.
Responses to the commercial, and show, have included role-playing blogs, fan art, videos, and fanfiction. Like many anime shows with a predominantly male cast, it has garnered a large following of yaoi fans. The series is know for it's fanservice focusing on male characters.
