Audio Tapes

Mr. Shersby
asked the Minister for Trade how many blank audio tapes having a running time exceeding 15 minutes are sold annually.

Dr. Vaughan
The only information is published by the British Phonographic Industry Ltd., which estimates, on the basis of extensive research, that 73·4 million blank audio tapes with a running time exceeding 15 minutes were sold in the United Kingdom in 1981.
