2013 International CES
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.
