One of the world's largest technology shows kicks off this week in Las Vegas. The Consumer Electronics Show (CES) brings together 150,000 people and 20,000 new products.
The annual fair has been running for 45 years, in which time it has seen the introduction of many of the consumer technologies we now take for granted.
However, not every launch has met with the same level of acclaim or success.
Explore our gallery of some of the big CES debuts of the last four decades ...and decide whether they were a hit or a miss.
