HobbySpace is a free social networking service launched in the UK in August 2007. The tag line for HobbySpace is …get involved.

The aim of HobbySpace is to encourage people to take part in activities in their free time and helps people with similar interests to find clubs and societies and meet and socialise with one another. This is particularly true in the case where an individual moves to an unfamiliar part of the country, looks to start up a new hobby or wishes to partake in an activity that they have since lost touch with.

The initial idea for HobbySpace was based around trying to find sports clubs and teams and for sports clubs to promote themselves and keep in touch with potential and existing members. This initial premise was expanded because of the observation that a large proportion of activities and pastimes aren't sport related and that the same person that plays a sport may also have a keen interest in other pursuits such as music or literature.

As a result, the current format has the lists ten different categories in which clubs should associate themselves with. The names and the main divisions of the categories are based around the way that The University of Sheffield's Union of students chose to categorise their clubs and societies. This is due mainly to the fact that three of the four co-founders of HobbySpace attended The University of Sheffield.
