Does my Roku® streaming device have an internet web browser?
Your Roku® streaming player or Roku TV™ provides you with access to stream video and music from the internet and does not provide the ability to browse the internet on your television.
Roku Channel Store
Just like your smartphone has an “app store” for installing new applications, you can access the Roku Channel Store on your Roku streaming device to add new “channels”. Channels are applications for your television; popular channels include Netflix, The Roku Channel, Apple TV, Vudu, Hulu and Showtime. Although some channels must be purchased or require a paid subscription, many others allow you to watch movies and TV shows for free.
When you want to add a channel, game or other app, learn how to use the Roku Channel Store to access your favorite movies and TV shows.
