Sony chief Kaz Hirai has attempted to spike persistent speculation that his company is looking for a buyer for its movie and TV unit, Sony Pictures Entertainment. In a statement, Hirai said on Tuesday, There is absolutely no truth to rumors that Sony's entertainment businesses are for sale. ... Sony is comprised of electronics, entertainment and financial services businesses, and our entertainment companies have a stable business foundation and are poised for future growth. There is no reason to sell these industry-leading businesses and no consideration is being given to the idea. Nevertheless, no movies are currently in production at Sony's vast lot in Culver City as the studio scrambles to find partners for its 2013 production slate.
