This is the 40th anniversary of the show, which has grown eight-fold since 1967. The event now hosts 2,700 exhibitors and more than 150,000 attendees. Groundbreaking technologies are unveiled to the world every year.

In 2005, Internet-based television made its debut and 1998 saw the introduction of high-definition TV. The camcorder and compact disc player debuted at CES in 1981 and conventioneers ogled over the videocassette recorder in 1970.
