CES gadget show: How watching TV will change in the 2020s

What will watching TV be like in the 2020s? In the midst of new gadgets and glitz, the CES tech show in Las Vegas aims to offer some answers, many of which boil down to more streaming and more efforts to glue you to your phone.

The show's keynote addresses, once dominated by computer and chip makers, are featuring executives from TV networks NBC and CBS and upstart video services like mobile-focused Quibi and free streamer Tubi this year. Topic one will be the streaming wars — not to mention mounting costs for consumers who want access to everything — as giants NBC Universal and WarnerMedia prepare to join the clash with Netflix later this year.

Some companies also promise a big new push into "bite-sized" video designed to draw mobile viewers from YouTube, despite the fact that a similar effort foundered several years ago.

CES, formerly known as the Consumer Electronics Show opened yesterday with two days of media previews. The show floor opens tomorrow through Friday. According to its organizers, more than 170,000 people are expected, with 4,500 companies exhibiting. The show takes place across a sprawling set of hotels and convention centers equivalent to more than 50 football fields.
