Jennifer Maas TV Business Writer Sony Pictures Entertainment communications chief Robert Lawson has been promoted to head of all corporate communications for its Tokyo-based parent Sony. The choice to move Lawson, who joined Sony amid the infamous cyber attack and email leaks at the entertainment group in 2014, into the top corp comms role is indicative of Sony’s significant focus on its entertainment divisions within the company’s larger portfolio; movies, music and gaming accounts for more than half of Sony’s revenue and profit.
