A ROKU device will make a dumb TV smart. These devices offer 1080i (HD) on the low end and 4K on the high end via HDMI port. This will give you access to TV channels streaming over the internet which can aid in "cutting the cord". Roku comes built into some smart TV's but the devices below will plug into any TV with HDMI inputs.
Gain access to independent news channels like Real America's voice and The Young Turks. Both channels have apps for ROKU. Incidentally, both are available out of the box on a Samsung Smart TV.
Roku offers its own operating system not that of Samsung's Tizen or Amazon's fire stick. Unfortunately, ROKU's do not have a built in web browser.
A ROKU device can connect to the internet via a WiFi network connection. Internet radio apps are available on ROKU such as Shout cast and TuneIn. Good Rock Radio is available on either apps. Browse 50+ Roku streaming devices below.
