Television was now beginning to spread over the country and, as a result, the tunable receiver appeared. It was more usual, though, to provide interchangeable tuning units for the various channels. In anticipation of VHF sound broadcasting, the provincial television stations were fitted with a superstructure carrying a slot aerial.

At the British Sound Recording Association's exhibition 33.33-rpm records (which had been exported for some time) made a first appearance. In addition to longer playing time they offered, thanks to the use of improved moulding material, lower surface noise, increased dynamic range and longer life.

'There may possibly be a sufficiently conducting layer in the upper air'. Oliver Heavyside, the centenary of whose birth was celebrated in 1950

In brief: centenary of Heaviside's birth; television boom in America (2.5 million sets sold in 1949).
