The Independent Television Areas at the beginning of 1963 include 96 per cent of the population. The shaded areas are within the “fringe” contours of the Authority’s 22 transmitters (¼ Mv/m). There is, in addition, much satisfactory viewing in the white areas, and in fact it is only in the extreme north and north-west of Scotland and the mountainous centre of Wales that there is no effective provision. The darker shading shows the areas within reach of more than one ITA transmitter.
