Social networking giant Facebook has partnered with the US television network ABC for a non-stop live streaming of both the Democratic and Republican National Conventions.

The Republican National Convention started in Cleveland, Ohio on Monday night and will run till Thursday while the Democratic National Convention is set for July 25-28 in Philadelphia, Pennsylvania.

Not just live streaming, Facebook will provide in-depth coverage of both the events, Engadget reported on Monday.

Earlier, micro-blogging site Twitter had signed a deal with the US television network CBS to stream both the conventions.

Twitter has permission to broadcast the CBSN feed - the company's 24-hour digital news streaming service - and anyone online can watch for free even if they do not have a Twitter account.

Social networking giant Facebook also announced its support to App Event Optimisation across Facebook, Instagram and its Audience Network from Tuesday, promising more installs of apps and actions within the app.

Launched in 2012 on Facebook, mobile app install ads allow developers to advertise their apps inside the social network's properties.

Since then, quite a few updates have been made to this advertising tool, including customised calls to action such as "Open Link," "Use App," and "Play Game," along with video support and the launch of a cost-per-action (CPA) bidding mode.
