Japanese electronics and entertainment company Sony Corp. said its profit dropped 84 percent in October-December as losses in its movie division offset healthy results in its video game business. Tokyo-based Sony, which makes the PlayStation 4 game machine and Bravia TVs, reported a fiscal third quarter profit of 19.6 billion yen ($174 million), down from 120.1 billion yen the previous year. Quarterly sales slipped 7 percent to 2.4 trillion yen ($21.3 billion), mainly because of unfavorable foreign exchange rates, the company said Thursday. Sony also lowered its full year fiscal profit forecast because of the $962 million write-down in its film division, stemming from its acquisition of Columbia Pictures in 1989.
