Grownups is a BBC Three sitcom written by Susan Nickson, who also created hit BBC Three sitcom Two Pints of Lager and a Packet of Crisps. It follows the trials and tribulations of a group of twentysomething friends in Manchester, facing the decision to either settle down or carrying on partying. The first episode aired on 7 May 2006 on BBC Three and appeared at number eight on the Broadcasters’ Audience Research Board top ten of most watched BBC Three programmes for that week. The show made only one more entry on the chart for the rest of the first series, when it reached number nine, some two weeks later. A second series was produced, with studio recordings taking place between May and July 2007. The first two episodes aired back-to-back on BBC Three on Sunday 5 August. Unlike the first series, the second series displayed more adult humour, including more intense sexual references. The first episode of the second series appeared at number eight in the BARB weekly top ten for BBC Three, with the second episode which aired immediately afterward, at number nine. A third series was commissioned by the BBC and tickets to see live filming went on sale on the official BBC Tickets website in September 2008. The first episode of the third series aired 13 January 2009.
