In 1991, a USA cable television company launched a television programme, aimed at high-school teenagers, that shows ten minutes of current affairs plus two minutes of advertisement. The schools are each given around $50,000-worth of television and video equipment in return for a three-year contractual agreement to show at least 90% of the programmes in all classrooms that have television sets without interruptions or editing. By April 1991, the programme was in 8,000 schools, providing an audience of 5 million teenagers.
