John Logie Baird (1888-1946), the Scottish television pioneer, produced the first widely available television sets in 1930, about the same time that the BBC began regular television broadcasts. Until the mid 1930s, transmisions were made only up to 30 line definition using the regular medium wave (AM) band, which could be received in the UK and parts of Europe. However, rapid progres in electronic technology and the invention of the 'Emitron' camera tube by EMI in 1935, scanning on up to 405 lines, soon made Baird's 30 line mechanical system obsolete. The first scheduled electronic broadcasts were made from the new London Television Station at Alexandra Palace in 1936.
