There is no charge to add a channel from the Roku Channel Store to a Roku streaming device. Available channel selections include free content, subscription-based content and content that is authenticated through a cable or satellite provider.
Roku offers channels in many categories, including kids, family, news, weather and sports channels. Subscription services, such as Netflix, Hulu Plus and Amazon Instant Video, provide channel apps, which the user accesses with his login credentials. Some cable network channels provide access to video clips and full episodes of their content. Not all cable providers are participating providers, which allows authentication and access to the listed content.
