What are some of the biggest collaborative projects that exist which started on social media from the last 3 years?

I'm in a 100s level tech intro course for the tech illiterate. So this is the q i was given but i'm having trouble finding results... i'm not a great researcher, so i was wondering if you guys can help.

question itself:

Social networiking now is about so much more than keeoing up ro date with your friendships. Crowdsourcing is one such example. Discuss some of the biggest collaborative projects that exist because of social media from the last 3 years.
