GameStop (GME 1.50%) isn't just surviving as the video game industry marches toward a digital sales model -- it's thriving. In the video below, Fool contributor Demitrios Kalogeropoulos explains how. With game publishers like Activision Blizzard (NASDAQ: ATVI) and Electronic Arts (EA 0.02%) reporting record digital revenue, GameStop just managed its best sales results in years. Sure, the retailer had some help from Take-Two Interactive (TTWO 1.26%) and its blockbuster Grand Theft Auto V release.

But GameStop also logged steady growth in its mobile and digital initiatives as well. And, most importantly, the company is making full use of trade-in business to give it a critical pricing advantage over competitors. That points to continued outperformance for the retailer through the holiday season, Demitrios argues.
