BuzzFeed is a website that combines a technology platform for detecting viral content with an editorial selection process to provide a snapshot of "the viral web in realtime." Cofounded in 2006 by Jonah Peretti (who is also cofounder of The Huffington Post), BuzzFeed is located in Manhattan, New York in the Flatiron District.

In 2012, Ben Smith of Politico was hired as editor-in-chief.

The BuzzFeed homepage consists of a time-sequential list of posts from users and staff members. The content of the posts is usually either a video, image, or link. These posts are the site's attempt to capture the essence of viral media currently resonating on the web. On Fridays, the website hosts a battle, where users are challenged to post the best, most time-wasting Flash game. Other posts are compendiums of memes or images that are all similar to each other in some way. Occasionally there are quizzes, but these posts are infrequent.

Every registered user of BuzzFeed has a homepage that contains links to their most recent contributions to the site. There is also a brief bio section and a scoreboard of how many times these users posts have been featured on the homepage or awarded "Gold Stars" by the staff.
