The paper illustrates this recent growth and draws the following conclusions. Satellite will continue to be the main vehicle for international video communications, with the growth of occasional transmissions continuing and satellite television becoming commonplace by the mid 1990s. Primary market sector demand will be for private transponder leases for both of these purposes. Satellites themselves will change by offering more specialised footprints, greater transponder flexibility and higher transmission frequencies, and space platforms will be used to overcome some of the congestion in the geostationary arc. As satellites become more powerful, there will be a corresponding fall in the size of earth stations: opening up new corporate markets and altering the way TV news and sport is gathered. Private sector investment will penetrate both space and ground segments as PTTs continue to be unable to match their public responsibilities to market demand.
