Digital giants are increasingly dominating the global advertising market.
In 2015, Google, Facebook, Baidu, Yahoo, and Microsoft accounted for 19% of all the global ad spend flowing through all media, according to media agency ZenithOptimedia's 2016 "Top Thirty Global Media Owners" report.
The report ranks the world's biggest media companies in order of revenue generated in financial year 2013, the latest year for which it has consistent revenue figures for all the publicly-listed companies. Media revenue includes advertising but also things like circulation revenues for newspapers and magazines.
All the familiar names are in there as well as some huge foreign entities you may not recognize.
Time Inc. used to be the magazine division of Time Warner, but was spun out as a standalone company in June 2014.
Its most well-known titles include Sports Illustrated, Time Magazine, and InStyle.
ZenithOptimedia notes that Time generates the majority of its revenues (53% in 2015) through advertising and that it has suffered from the overall decline in magazine circulations. "Time Inc.'s revenues declined at an average rate of 4.1% a year between 2011 and 2015."
This Japanese media group owns the eponymous daily newspaper, The Yomiuri Shimbun, which is the most popular daily newspaper in the world, with a circulation of more than 9 million copies.
The company also owns English language daily The Japan News and it owns a 14.6% stake in the Nippon TV network, publishing group Chukoron-Shinsha, and Japanese professional baseball team the Yomiuri Giants.
ProSiebenSat.1 owns 15 TV stations across Germany, Austria, and Switzerland, reaching around 42 million households in total.
The company is currently working to grow its "digital and adjacent" business, which accounted for 26% of total revenue in 2015.
