BuzzFeed Inc. is eliminating 15 percent of its headcount across the company, the latest pullback for digital-media sites dealing with a challenging advertising market. As it trims staff, BuzzFeed has been examining the \u201cthe evolving economics of digital platforms,\u201d Chief Executive Officer Jonah Peretti said in a memo to employees. \u201cWe\u2019ve developed a good understanding of where we can consolidate our teams, focus in on the content that is working, and achieve the right cost structure.\u201d The cutbacks are part of a wave of media layoffs. Verizon Communications Inc. said earlier Wednesday that it would be cutting about 7 percent of its digital-media operations, a business that includes AOL, Yahoo and the Huffington Post. Gannett Inc. also has been laying off journalists from its collection of newspapers. BuzzFeed, a pioneering site that spans hard news, personality quizzes and listicle-style features, was long seen as a way for journalism to prosper in a post-print era. But growth alone hasn\u2019t been enough to ensure success, Peretti said in his memo.

In his memo, Peretti promised to share more about the company\u2019s plans in the next few days. \u201cEven though I\u2019m confident this is the right business decision, it is upsetting and disappointing,\u201d he said.
