Buzzfeed published nearly 70,000 articles in 2014

"We wrote a simple crawler (see code) using the Priceonomics Analysis Engine, our tool that makes it easy to crawl and analyze web data, and then analyzed what the sources were used for the images that BuzzFeed includes in their articles.  In the last year, BuzzFeed published about 69,000 articles, included 830,000 images/videos with attribution strings, and linked to approximately 74,000 distinct sources.
However, just 25 sources made up 62% of BuzzFeed’s content. While the Internet is a huge place, Internet Culture is birthed in just a few areas. What are these sources?
The number one place that BuzzFeed sources its images from is Tumblr. This is where The Dress was discovered. Instagram, Getty Images, and Youtube round out the top 4. This analysis isn’t perfect, however, as it ignores content that BuzzFeed embeds without putting an attribution link under it (Twitter embeds for example don’t need an attribution link since they are clearly from Twitter). A number of these sites simply provide stock photos."

Note - This works out to nearly 200 articles a day, which seems high, but will include all the editions of Buzzfeed, plus amateur 'community' posts.
