Microsoft has taken another important step forward in its acquisition of Activision Blizzard, as the UK Competition and Markets Authority (CMA) revealed that it is now paying less attention to the deal. The UK competition watchdog changed its attitude about Microsoft's $75 billion deal to buy Activision Blizzard, removing some of the barriers to approval of the deal. The UK Competition and Markets Authority said on Friday that the deal would not drastically reduce competition in the console market. Activision Blizzard closed 5.91% higher and traded US$2.07 billion, making it 15th in US stock turnover on Friday.
