Legendary programming Q&A site Stack Overflow is being acquired by Prosus N.V., Europe's largest tech investment firm. According to a press release on Prosus' website, the two companies entered into a definitive acquisition agreement yesterday.

According to Amazon Alexa web analytics, Stack Overflow is the 46th most heavily engaged site in the world. Since 2008, the site has served as the first stop for developers searching for answers to their programming-related questions—and eventually, their non-programming-related questions, as the Stack Exchange network of sites expanded into categories including culture, recreation, arts, science, business, and more.
