The following video is part of our "Motley Fool Conversations" series in which Chief Technology Officer Jeremy Phillips and senior technology analyst Eric Bleeker discuss topics across the investing world.

Video game sales in December are out, and they're brutal. Hardware sales fell off a cliff while software saw a swoon of its own. In total, industry researcher NPD reports that the all-important month of December accounted for 23% of industry sales, well below the 10-year average of 28%.

While that's a bad omen for the industry, it also highlights the changing face of video games. As sales move online and home entertainment integrates mobile-centered operating systems like Android and Apple's iOS, game sales and other entertainment sales will be increasingly intertwined. That means the old ways of analyzing industry sales could continually become more meaningless.

Increasingly, mobile is the force threatening to bring video game sales screeching to a halt. To help investors navigate the mobile revolution, The Motley Fool has just released a free report on mobile named "The Next Trillion Dollar Revolution" that details a "hidden" component play inside mobile phones that's also absolutely dominating the exploding tech market in China. Inside the report, we not only describe why the mobile revolution will dwarf any other technology revolution seen before it, but we also name the company at the forefront of the trend.
