A considerable number of German broadcasting interests also migrated early to ASTRA and SES's evolving system was soon enabling diverse programme services in a wide variety of languages, ushering in a new era of themed private television and radio channels as alternatives to the general entertainment models commonly associated with terrestrial broadcasting.
ASTRA 1D inaugurated a significant new phase of technological development, for it is the first satellite in the system that can be operated in the BSS frequency band (Broadcast Satellite Services) reserved for future digital transmissions.
