agreed. "Various subliminal stimuli are broadcast with and keyed to the overt subject matter. The home receiving unit contains feedback sensors which determine the viewer's reaction to these stimuli, and intensify some while playing down others in order to create complete emotional rapport between the viewer and the subject matter. EmpaVid, in other words, is a system for orchestrating the viewer's emotions. The home unit is self-contained, semi-portable and not significantly bulkier than the standard TV receiver. EmpaVid is compatible with standard TV receivers—except, of course, that the subject matter seems thin and vaguely unsatisfactory on a standard receiver. So the consumer shortly purchases an EV unit." It pleased Sollenar to spell out the nature of his prize. "At a very reasonable price. Quite so, Mr. Sollenar. But you had several difficulties in finding potential licensees for this system, among the networks." Sollenar's lips pinched out. Mr. Ermine raised one finger. "First, there was the matter of acquiring the patents from the original inventor, who was also approached by Cortwright Burr." "Yes, he was," Sollenar said in a completely new voice. "Competition between Mr. Burr and yourself is long-standing and intense." "Quite intense," Sollenar said, looking directly ahead of him at the one blank wall of the office. Burr's offices were several blocks downtown, in that direction. "Well, I have no wish to enlarge on that point, Mr. Burr being an IAB member in standing as good as yours, Mr. Sollenar. There was, in any case, a further difficulty in licensing EV, due to the very heavy cost involved in equipping broadcasting stations and network relay equipment for this sort of transmission." "Yes, there was." "Ultimately, however, you succeeded. You pointed out, quite rightly, that if just one station made the change, and if just a few EV receivers were put into public places within the area served by that station, normal TV outlets could not possibly compete for advertising revenue." "Yes." "And so your last difficulties were resolved a few days ago, when your EmpaVid Unlimited—pardon me; when EmpaVid, a subsidiary of the Sollenar Corporation—became a major stockholder in the Transworld TV Network."
