Episodes

Production

The season was produced by 20th Century Fox Television and Ryan Murphy Television, and was aired on Fox in the US. The executive producers were Dante Di Loreto and series creators Ryan Murphy and Brad Falchuk, with John Peter Kousas and creator Ian Brennan acting as co-executive producers. The first two episodes were co-written by Murphy, Falchuk and Brennan; all other episodes were written by them individually. Murphy and Falchuk also directed several episodes, while other episodes were directed by Elodie Keene, John Scott, Paris Barclay, Bill D'Elia and Alfonso Gomez-Rejon. Joss Whedon guest-directed the episode "Dream On". The pilot episode was broadcast as a preview of the season on May 19, 2009. The series returned on September 9, 2009, and after three episodes, Fox picked Glee up for a full season on September 21, 2009. The initial run of thirteen episodes aired until December 9, 2009, with the series then taking a mid-season break until April 13, 2010. After airing on Wednesdays at 9 pm (ET), the first season moved to Tuesdays in the same timeslot for the final nine episodes. The commissioning of a second season was announced on January 11, 2010, with the production of a third season announced on May 23, 2010.

The series features numerous musical cover versions performed on-screen by the characters. At the beginning of the season, Murphy intended for the performances to remain reality-based, as opposed to having the characters spontaneously burst into song. As the season progressed, however, Glee began to utilize fantasy sequences, with paraplegic character Artie imagining himself dancing to "The Safety Dance", and six separate characters performing a fantasy version of "Like a Virgin". The first thirteen episodes of the season averaged five songs per episode. For the final nine episodes, the number of performances increased to eight. Murphy believes that many of the songs were "really fun and successful", however the production team intend to return to five songs per episode for Glee second season, in order to return focus to the characters.

When seeking to attain the rights to songs, early in the season Murphy was often requested to send out advanced scripts, but refused, not wanting to set a precedent for record labels having creative involvement in the show. Singer Rihanna offered her single "Take a Bow" for use at a reduced licensing rate. Madonna granted the show rights to her entire catalogue, and the tribute episode "The Power of Madonna" features Madonna performances exclusively.

In total, five soundtracks were released to accompany the first season. Three albums released over the course of the season (Glee: The Music, Volume 1, Glee: The Music, Volume 2, and Glee: The Music, Volume 3 Showstoppers) compiled various songs throughout the series, while two EPs (Glee: The Music, The Power of Madonna and Glee: The Music, Journey to Regionals) were released on the same day as the respective episodes aired. Journey to Regionals did not release any official singles, while the remaining four albums were fully released as singles. Following the completion of the season, the Glee cast performed a 13-date concert tour in North America, Glee Live! In Concert! By its conclusion, tickets for all 13 performances had sold out, grossing $5,031,438.
