On display this year was connectivity and integration for consumers based on about 10 years of incremental and sometimes hardly noticed baby steps. There are three big developments that are enabling the vast majority of scenarios on display at CES 2019:

Any screen/speaker can play any streaming media.

Any device can be turned on/off/controlled by voice.

Any device can have a radio and connect to any other device with a radio.

Fun times ahead.

Lots of pictures.
