One major area of mobile computing that is both profitable and popular is gaming. Marissa Mayer understands this. That's why she gave the okay to pick up mobile gaming company Loki Studios. Founded by students and Stanford, Loki Studios focused on "combining engaging game design with the features unique to the next generation of mobile devices." No one's sure what the team's roll will be once at Yahoo!, but the company did say that it is "thrilled to be joining the exceptional folks at Yahoo!. We believe fully in their commitment to creating outstanding mobile products."
