Dish is expanding its hardware lineup today with the launch of a new 4K streaming stick, the AirTV Mini, designed to make it easier for cord cutters to access from one user interface its live TV service Sling TV, plus Netflix and over-the-air channels. The Android TV-powered device is meant to complement an existing setup that already includes an OTA digital antenna and an AirTV Wi-Fi-enabled network tuner, the company says.
