LAS VEGAS: The CES electronics trade fair has often seen important technology premieres over the past 45 years. Take the first video recorder, shown in 1970, or the first DVD in 1996, then the first televisions with OLED advanced screen technology in 2008.

That slowed down a little due to the pandemic over the past three years but now, 3,100 exhibitors from 173 countries are vying for CES visitors' attention. Some of the key themes on show in Las Vegas may dominate the tech year ahead.
