The Roku Streaming Player is a series of set-top boxes manufactured by Roku, Inc. Roku partners provide over-the-top content in the form of channels. A Roku streaming device gets data via a wired or Wi-Fi connection to an Internet router. The data is output via an audio cable, video cable or both signals over an HDMI cable. The device can be connected to any television set with appropriate input connections. Roku calls a stream source on the internet a channel. Channels can provide on-demand content or live streaming video. Both free and paid channels are available; they include services such as PBS, YouTube, Netflix, Hulu Plus, Amazon Instant Video, Crunchyroll, WWE Network, HBO Go, and others. Users can add or remove different channels through the Roku Channel Store. Some games are also available for the devices. In May 2011, Roku stated the devices had over one million viewers and had delivered 15 million channel downloads.
