The Vectrex is displayed first time to the public at the Summer Consumer Electronics Show in Chicago, USA. The first CES was held in June 1967 in New York City. It was a spinoff from the Chicago Music Show, which until then had served as the main event for exhibiting consumer electronics. The event had 17,500 attendees and over 100 exhibitors; the kickoff speaker was Motorola chairman Bob Galvin. From 1978 to 1994, CES was held twice each year: once in January in Las Vegas known as Winter Consumer Electronics Show (WCES) and once in June in Chicago, known as Summer Consumer Electronics Show.
