Time Inc. has acquired a 51 percent stake in MedioTiempo, a Mexican soccer site that claims to be the biggest sports site in the country. The deal was mentioned in a quote from Time Inc. spokeswoman in an AdAge piece about the company’s portfolio strategy. A rep from the company, the magazine publishing arm of Time Warner (NYSE: TWX), confirmed to us the deal, and explained that the site was launched in 1999 by three entrepreneurs with a passion for soccer. The actual acquisition was finalized in the past month. In addition to claiming the mantle as the biggest sports site in the country (their own claim), the company also says its the fifth biggest standalone site in any category.
