Hasbro's growing revenue.

The Hasbro company announced on Monday that its games unit, which includes Magic, Monopoly, and Twister, among others, reported a 19% sales gain in the second quarter. Hasbro executives say Magic is the biggest brand in its $1.2 billion games portfolio, without drilling into specifics, and said in its annual report that 2012 marked Magic’s fourth straight year growing revenue by 25% or more. It’s a phenomenal performance for a game celebrating its 20 anniversary, and much of that is thanks to Hasbro subsidiary Wizards of the Coast’s ability to successfully take Magic from a physical trading card game into the digital world since 2008. Wizards of the Coast, which is also behind Dungeons & Dragons and the Duel Masters franchise, may make $445 million in sales this year, estimates Sean McGowan, an analyst at Needham & Co. Hasbro bought Wizards in 1999.
