What does Sony’s purchase of MGM mean to the movie business? “MGM has Hollywood’s biggest movie library, with some 8,000 titles, though Sony intends to close the company’s ongoing studio operations, with the exception of the James Bond and Pink Panther franchises. The new, combined group will own half of the colour movies ever made. Sony, which is struggling with low margins in its core consumer-electronics division, is also trying to amass content that it hopes will drive sales of its electronic goods.” The new landscape could change the way studios make money.
