The annual convention will see the likes of Sony, Samsung and LG unveil new products, alongside thousands of other firms showing off their latest innovations at the four-day event. Artificial intelligence, 5G and robotics are expected to be among the biggest talking points when the world's largest technology show - CES - begins tomorrow. It opens on Tuesday January 7 in Las Vegas. High-profile figures from Apple and Facebook will also appear together on stage during the show to discuss the tech industry's approach to data privacy - a topic the firms have previously clashed over in the past. CES is a key date in the industry calendar, with more than 170,000 people expected to attend and more than 20,000 new devices set to be unveiled.
