I think I have to speculate as to what would happen. Congress in the United States recommended the elimination of public performance for schools in the United States a number of years ago. That was eventually incorporated into their Copyright Act. As a consequence, most of the major providers and creators of audiovisual material for the classroom—organizations such as Encyclopedia Britannica, American Education Corporation, McGraw-Hill Films, and Learning Corporation of America, which were all companies generating $50 million or $60 million worth of business per year—went out of business. They no longer exist. So they would disappear. All of the jobs would disappear. Of course, there are very few corporations left that produce material specifically for the classroom.
