Question
How to buy a VCR?
Answer
Home video systems had previously been available, but they were open reel systems (most notably made by Sony) and were expensive to both buy and operate. They were also unreliable and often only recorded in black and white. The VCR system was easy to use and recorded in colour but was still expensive: the N1500 recorder cost nearly £600 in the United Kingdom when it was introduced in 1972, the equivalent of more than £4500 today.
