The necessity for better satellite television programming than TVRO arose in the 1980s. Satellite television services, first in Europe, began transmitting Ku band signals in the late 1980s. On 11 December 1988 Luxembourg launched Astra 1A, the first satellite to provide medium power satellite coverage to Western Europe. This was one of the first medium-powered satellites, transmitting signals in Ku band and allowing reception with small(90 cm) dishes for the first time ever. The launch of Astra beat the winner of the UK's state Direct Broadcast Satellite licence, British Satellite Broadcasting, to the market, and accelerated its demise.
