For the first time in a long time, Microsoft didn’t kick off the CES electronics show with a keynote address—last year, the software giant announced it would sit out the 2013 edition. With Apple, Microsoft, and Google all absent, it’s been Samsung’s show so far. Here’s what happened on the first day of the industry’s largest convention, which will run through Friday. Samsung wowed on day one, introducing an ultra high-definition, 110-inch TV, an internet-connected refrigerator with a touchscreen and apps, and a new Galaxy Tab 10.1 inch tablet. Its F8000 TV will be between 46 and 75 inches and can be controlled with a users’ voice; and it will be Internet- and social networking-enabled. The company’s “Smart Hub” will act as a kind of home screen for TV watchers, allowing people to use hand gestures to navigate through different TV options.
