Microsoft Corp. agreed to buy Activision Blizzard Inc. in a $68.7 billion deal, uniting two of the biggest forces in video games to create the world's third-biggest gaming company. In its largest purchase ever, Microsoft will pay $95 a share in cash for one of the most legendary gaming publishers, known for titles like Call of Duty and World of Warcraft but which is also grappling with a cultural upheaval over its treatment of women. Activision Chief Executive Officer Bobby Kotick will continue to serve in that role only until the deal closes, a person familiar with the deal said. It's unclear what position, if any, he would take afterward. Once the transaction is completed, the Activision Blizzard business will report to Phil Spencer, who was promoted along with the deal to CEO of Microsoft Gaming.
