Yahoo makes a push for mobile game industry by acquiring Stadeon a company that has the technology to turn internet-connected phones into game clients. People could be playing against other people connected to internet no matter mobile or fixed line.
Convergence is the everlasting rumor in the ranks of mobile devices. This plays straight into that pocket. Yahoo is already strong in internet content distribution, not that much in content creation. Sensible move from Yahoo as they now are able to strengthen their mobile front and take their net services increasingly to phones. Time schedule is very tight, since we can expect to have the Yahoo branded online mobile games by the end of the year.
