Takeover talks between Electronic Arts and Take-Two have come to an end, the two video game software companies announced Sunday. The news comes some seven months after EA made its initial unsolicited offer to purchase the “Grand Theft Auto” developer for $26 per share, a deal that would have brought Take-Two’s shareholders about $2 billion. The rival publishers had only recently come to the negotiating table for formal talks following EA’s decision to allow the offer to expire.
