*240-line versus [[405-line]] [[television]] broadcasts. In 1936, the [[BBC One|BBC Television Service]] commenced [[television broadcasting]] from [[Alexandra Palace]] in North London. They began by using two different [[television standards]] broadcasting in alternate weeks. The 240-line [[John Logie Baird|Baird]] sequential system was broadcast using a mechanical scanning apparatus. In the intervening weeks, [[EMI]]-[[Marconi Company|Marconi]] broadcast in 405-line interlaced using fully electronic cameras. Early sets had to support both systems, adding to their complexity. It was the BBC's intention to run the two systems side by side for a six-month trial to determine which would be finally adopted. The BBC quickly discovered that the fully electronic EMI system had a superior [[picture quality]] and less flicker, and the camera equipment was much more mobile and transportable (Baird's [[Intermediate film system|intermediate-film]] cameras had to be bolted to the studio floor as they required a [[water supply]] and [[drainage]]). The trial concluded after only three months after Baird's studios had lost most of their equipment in a fire.
