On this week's Tech Weekly, Aleks Krotoski, Bobbie Johnson and Jemima Kiss chat with Adam Buxton and Joe Cornish – the comedy duo collectively known as Adam and Joe – who have been promoting user-generated content on television since the mid-1990s.

They offer their insights into what makes content producers tick, and a few suggestions on how to make the most of the web as a platform for distribution.

Jemima interviews Andy Bower, acting Head of Broadcast Research and Innovation at Kingswood Warren, the BBC's locus of new technological developments.

Over the years Kingswood Warren has brought the world colour TV, Freeview and Ceefax, among other things. With the land set to be sold and the team set to be relocated to Salford in 2010, we find out whether the move threatens the corporation's R&D output, and whether licence fee payers should be better informed of the work it does.

All this plus the latest on the Apple iPhone, the hackers bringing down Microsoft Vista and your views on these stories and more.
