Time Warner has struck a multiyear advertising pact worth as much as $300 million with consumer products giant Unilever, The Post has learned.

The three-year deal spans Time Warner’s magazine, television and Internet properties and includes a digital tie-in with Time magazine’s iPad app. The ads will feature Unilever brands ranging from Dove and Caress soap to Hellmann’s mayonnaise and Bertolli pasta.

The companies are set to announce the deal as early as today.

The deal was struck by Time Warner’s Global Media Group, run by Mark D’Arcy.

The Time Warner deal is worth an estimated $300 million, based on Unilever’s past spending. Kantar Media, which tracks ad expenditures, estimates that Unilever spent $119 million with the media giant in 2009.
