SAN BRUNO, CA – With the announcement of a presidential run by Newt Gingrich on Facebook and Twitter, the role of social media as the media of choice for politicians is rising. 

According to Olivia Ma, who manages news and politics for YouTube, Presidential politics on YouTube, which began in earnest with President Obama’s campaign launch announcement in 2007, will be an increasingly important place for politics, policy discussion and dialogue.

This is the fourth and final segment of our conversation with Ma at  YouTube headquarters last month.
