While the format does vary, the common format is a long weekend over 4 days consisting of workshops, discussions, meetings and social events. Although being billed as a "bisexual" event, it is open to partners of bisexuals, supporters, non-bisexuals, non-definers, and anyone else interested in the issues around bisexuality. To that extent it can often be characterised as a nexus of the sexual freedom and queer movements. Since the late 1980s, BiCons have normally attracted between 150 and 250 participants.
Each year BiCon is organised by a different team of volunteer activists, sometimes under the banner of a local Bisexual group, sometimes as independents.
That following October the Edinburgh Bisexual Group took up the torch and ran an event called "Bisexuality and the Politics of Sex". This established the idea of conferences moving around the nation. The next was run by a bisexual women's group in London. By this point the communtity was starting to know what they wanted from BiCon - a chance to meet other bisexuals (and their allies) from across the country, discuss sexuality issues, relax in the company of likeminded folk and network.
Armed with an agreed purpose, for the next few years the conference alternated between venues in London and Edinburgh. Then in 1989 it branched out to Coventry. As well as being the first one outside the two capitals, it was also the first to be residential (previously, people from outside the host city had either booked accommodation privately or stayed with local attendees: 'crash space') and to use the name 'BiCon', in part because of the organisers' and venue's experience with SF Cons (Science Fiction conventions).
A range of cities and towns have hosted it since. Over time BiCon has evolved to fit with the needs of the community. The word 'conference' has been largely replaced by 'convention', but there is still a political and campaigning side to the event. In recent years the momentum behind the event has spawned a number of off-shoots, such as 'BabyBiCon', BiFest and the 'Bi Academic Conference', which have concentrated themselves on particular aspects covered by BiCon.
