The first high definition TV service

On 2 November 1936, the BBC began the world’s first ‘high definition’ television broadcast service. Back then, high definition was classed as a minimum of 240 horizontal lines rather than the 1080 horizontal lines of today’s digital high definition television. It was however, very much high definition when compared to earlier systems, like the one pictured above, which were only 30 lines.
