The season received generally positive reviews from critics.
The musical performances from the second season expanded on the success of the first season, with the show releasing five soundtrack albums and over one hundred digital singles.
The cast decisively broke the record for most charted songs by an act in the 52-year history of the Billboard Hot 100 with 156 appearances through the end of its second season.
Two singles, "Teenage Dream" and "Loser Like Me", were the first to have over 200,000 downloads in their first week of release in the US, and both charted in the top ten in the US and Canada, and have been certified gold in the US.
The season was nominated for twelve Emmy Awards, five Golden Globe Awards, five Satellite Awards and over fifty other awards.
Three DVDs have been released with episodes from the season: Glee – Season 2, Volume 1 featuring episodes one through ten, Glee – Season 2, Volume 2 featuring episodes eleven through twenty-two, and Glee – The Complete Second Season.
Mc Kinley High’s glee club and cheerleading squad budgets are cut to allocate more money for the football program and its new football coach Shannon Beiste (Dot-Marie Jones), so directors Will Schuester and Sue Sylvester scheme to get their money restored.
