Ok so it was my first time and apologies for not giving you enough information.  I am in London.  Channel 4 is a commercial broadcaster which aims to transmit programming not catererd for on other mainstream channels - its aim is allegedly to be a bit more edgy and intelligent though looking at their listings you'd be hard pushed to differentiate it from any of the other main broadcasters - BBC/ITV and more recently Channel 5.

I am going to be producing a series about the history of porn - it will be a three parter and at the minute the episode we are having trouble with is the first.  We are hoping to talk to people who were involved in 'amateur' or home porn in the 70s and 80s when camcorders first became widely available.  Ideally the people we will feature will be from the UK but I am happy to talk to anyone anywhere about this.   I hope this has given you a clearer idea of what I am looking for and hope you or someone else reading this might be able to help me.
