Etymology

Origin of crowdsource

First recorded in 2006; crowd 1 + (out)source

Explanation

When you crowdsource something, you call on the general public for help or ideas. For example, some companies crowdsource recommendations for the name of a new product. Social media is a good place to crowdsource: a request for assistance can attract a large number of volunteers. Social media posts have crowdsourced donations to help after natural disasters. The National Aeronautics and Space Agency (NASA) has crowdsourced the search for potentially dangerous asteroids. Amateur astronomers can volunteer to review NASA photographs of outer space, looking for any large asteroids that might be on a collision course with Earth. That’s a use of crowdsourcing we can all be thankful for.
