Charles and David Koch, the billionaire brothers who are major funders of Republican candidates and conservative organizations, now own a stake in Time Inc. On Sunday night, the Meredith Corporation announced that it is purchasing the company with the help of $650 million from a Koch equity fund. A Koch spokesman suggested this is purely a business decision, and Meredith has claimed the right-wing billionaires will not have a seat on its board or influence over the editorial decisions of the newly acquired magazines, which include Time and Fortune. But journalistsare rightfully skeptical that the Kochs would enter the embattled magazine publishing business if they didn’t view the investment as a way to advance their conservative principles.
