Digital screens have evolved over the last 80 years – Tom Mudd
On November 2, 1936, the British Broadcasting Corporation launched the first regular high-definition television service in the UK, broadcasting live from Alexandra Palace, London. The term ‘high-definition’ was used for this pioneering service in the 1930s, in comparison with earlier systems that were based on mechanical processes with as few as 30 lines of resolution – this has since been adopted again more recently to describe the new generation of communications media that display a substantially higher resolution than that of its predecessors.
