Caitlyn Jenner has had a year for the record books. Being that Bruce, her former self, was an Olympic decathlon champion, Caitlyn is no novice to the spotlight. America got to know Bruce through the 1976 Montreal Olympics, multiple endorsements, and then the E! hit Keeping Up With The Kardashians, but now knows Caitlyn from her own reality series I Am Cait. When @caitlynjenner joined Instagram in July, she broke the record for hitting 1 million followers in under four hours. As an outspoken trans activist, Caitlyn has become the public voice for the trans community in American pop culture.
