Reddit (stylized as reddit, ) is a social media and social news aggregation, web content rating and discussion website. Reddit's registered community members can submit content, such as text posts or direct links. Registered users can then vote submissions up or down to organize the posts and determine their position on the site's pages. The submissions with the most positive votes appear on the main page or the top of a category. Content entries are organized by areas of interest called "subreddits". The subreddit topics include news, science, gaming, movies, music, books, fitness, food, and image-sharing, among many others.
As of 2016, Reddit had 542 million monthly visitors (234 million unique users), ranking #11 most visited web-site in US and #25 in the world. Across 2015, Reddit saw 82.54 billion pageviews, 73.15 million submissions, 725.85 million comments, and 6.89 billion upvotes from its users.
Reddit was founded by University of Virginia roommates Steve Huffman and Alexis Ohanian in 2005. Condé Nast Publications acquired the site in October 2006. Reddit became a direct subsidiary of Condé Nast's parent company, Advance Publications, in September 2011. As of August 2012, Reddit operates as an independent entity, although Advance is still its largest shareholder. Reddit is based in San Francisco, California. In October 2014 Reddit raised $50 million in a funding round led by Sam Altman and including investors Marc Andreessen, Peter Thiel, Ron Conway, Snoop Dogg and Jared Leto. Their investment saw the company valued at $500 million.
