Hollywood, bidding fair to becoming a ghost town with the advent of tv, is now letting out its stays to breathe one hearty sigh of relief before settling down to the serious business of grinding out tri-di movies.

He pointed to the tridi where a large ostrich-like fowl was brandishing his pinions and lofting himself easily as he pranced about.
Interest in their home system was at fever pitch. The secretariat had arranged tridi FTL coverage from underneath the transparent track, so that viewers could observe the cell-by-cell approach.
Now—I want a run-through of the Ruhkarv report in comparison with the tridees from Xcothal.
Kosgro switched the three through the air and thrust in and out with them as I had seen swords used in tridee tapes made on primitive worlds.
Her quarters were as good as the guest facility in the Shankill Base, nothing gaudy but certainly substantial: bed, table, chairs, writing surface, tri-d screen, the customary audio-visual terminals.
Scile spent hours, many hours, listening to recordings of Ariekei speaking, watching trids and flats of encounters between them and the Ambassadors.
