Crowdsourcing

Crowdsourcing has become a household word, with crowdfunded products, businesses, art projects, nonprofits, and even new journalism models. Citizen scientists band together virtually to find new galaxies, count birds, and monitor water quality.

But the granddaddy of crowdsourced information sites is Wikipedia, which—somewhat ironically—can tell you that the Encyclopaedia Britannica, its predecessor and former go-to source for information, published its last print edition in 2012.
