The 4:3 format didn't gain recognition until 1936 when the BBC started its own 405-line TV broadcasts, curtailed by the Second World War two years later (see 'Vintage Bang & Olufsen products). Before this, the world's first TV broadcasts began life with only 30 lines per picture. Marconi's system - employing low-resolution representations, operated a vertically-scanned letter-box aspect ratio in order to allow the best match for head-and-shoulders views. The current trend towards widescreen - or 16:9 aspect ratios - began with the cinema.
