U.S. video game giant Electronic Arts Sunday said it had made an unsolicited $1.9 billion offer for "Grand Theft Auto" publisher Take-Two Interactive Software, escalating its battle with Activision for the title of biggest video game maker.

The Electronic Arts headquarters in Redwood City, California.

Electronic Arts said it had pursued the deal privately since December, and Take-Two Sunday immediately rejected the offer, a 50 percent premium to its Friday close, and accused EA of trying to scoop up a company in turnaround with an "inadequate" bid just before the publication of its next hit.
