The show first aired in September 2011 and was rated #10 in the Weekly Top 10 Programmes for the week of 3–9 October 2011. The second series of Hacker Time began airing on 6 August 2012 and instead of the guests being tricked onto the show, Hacker sends out Wilf and Herman to kidnap them and get them to come onto the show. The third series of the show started on 22 July 2013 where Derek books better guests than Hacker has in mind.
