If I have understood your question correctly, your Keywords "protests" and "boycotts" could be used very close to the term "Color revolutions". If this is the case then you can find relevant links on Google using keywords "Color revolutions", "Color revolutions Youtube" and so on.
The literature on the topic has grown in recent years, driven particularly by the use of social media in global protests , the Arab Spring and Segolene Royal (2007) and Obama (2008) presidential campaigns. The effect of social media --and the Internet at large in political campaigns is a very contentious topic (see Boulianne, Bimber, Bimber and Copeland and Cho et al. papers). Tthe Journal of Communication (2012) and the Communication Review (2012) published special editions to analyze the so called "Twitter .Revolutions". I also attach something about the latter.
