dealt with a number of storylines based upon serious issues. Given the large and established proportion of young viewers, some feel that the soap opera is an ideal platform to show a variety of issues affecting young people. Earlier episodes were focused on partying and relationships, but the focus quickly went onto issue-led storylines including mental health, rape and self-harm. Hollyoaks has become notable for being the first soap to address various social issues.

You get bits here and there and piece it together. It's exactly the sort of thing Hollyoaks should be doing, challenging its audience." In late 2009, it was announced that Hollyoaks would make another soap first by screening a flashforward episode. On 21 December 2009, the series' time-line moved forward six months into May 2010.
