A:Answer All of our TCL Roku TVs have a Roku operating system built-in. Roku is a streaming platform that offers many features, including thousands of streaming channels (apps) and over 500,000 movies and TV episodes. Some content is free while other content is subscription based or pay-per-view. You can go to www.Roku.com/whats-on to see what streaming channels and apps are offered through the Roku Channel Store. To search for a specific channel you would simply want to enter that information into the search section. In order to use the smart features of this TCL Roku TV, you would need to complete the guided setup. This includes connecting to the Internet via WiFi, creating a Roku account (completely free), and activating the TV (completely free). Hope this helps! Thank you, TCL Customer Support
