Google unlocked its Chromecast software development kit Monday, allowing app developers to push their apps or website content to the video streaming dongle. Prior to the update, Chromecast users had a minimal choice of apps as Google allowed select developers to create apps for its dongle. The Google Cast Software Development Kit (SDK) will open up the Chromecast to a whole new world of apps and functionality.

The previous SDK only allowed well-known companies like HBO, Pandora, and Netflix to create apps that utilized Chromecast's capabilities. Google, however, was persistent about adding support from third-party developers in the future. With the new SDK, developers can bring their content to the big screens. As a result, end users will have access to more TV shows, movies and music.

"We want to make it easier for that content to get to your TV, so today we're releasing the Google Cast Software Development Kit (SDK) for developers who want to build Chromecast support into their apps and websites," Ambarish Kenghe, Chromecast product manager and cast master, wrote in the company's blog post, Monday.

"Just be on the lookout for the cast button in your favorite apps and websites across Android, iOS and Chrome," he added.

Google launched the tiny HDMI Chromecast dongle alongside the Nexus 7 tablet at an event in San Francisco, last July. The video streaming dongle got a lot of attention for its functionalities and low price. The $35-Chromecast plugs into a TV or a larger screen for media streaming and is controlled via Android, iOS and web applications. Website support only works via Google Chrome extension, which can be added to your browser from the Chrome Web Store.
