Summary Box: Time Warner 4Q earnings edge up

THE RESULTS: Time Warner Inc. says net income rose slightly, and revenue rose 5 percent in the fourth quarter.

THE MAGICAL EFFECT: Time Warner got a boost from its movie studio, particularly the Nov. 11 home video release of the final “Harry Potter” movie. That was partly offset by a comparison with a quarter that included the November 2010 theatrical release of the next-to-last installment of the series.

THE FUTURE: The company expects growth to continue in 2012 even with the end of its lucrative Harry Potter franchise. Growth forecast for adjusted earnings this year topped Wall Street’s expectations.
