After first being introduced to Kurt Hummel (played by Chris Colfer) as he was being thrown into a dumpster on the series premiere of Glee, the Fox show tackled gay issues big and small, bringing LGBT storylines to the forefront. In 2010, Kurt met the swoontastic (and equally out) Blaine Anderson (Darren Criss), causing the audience to cry “squee!” into their Tumblrs and Twitter accounts at the same time. Blaine and the Warblers serenaded Kurt with Katy Perry’s “Teenage Dream,” and the Glee cast earned its best single sales week for a download with the song’s release (214,000, according to Nielsen SoundScan).
