A new category of games has been added to the arcade, Mochi Media games. These are the usual flash type games except they display a small ad or short video ad before playing. Usually on the video ads you can choose to 'skip ad' after 5 or 10 seconds have played. JUOT earns money (probably fractions of a cent) each time the ad is viewed or clicked. As with the google ads just ignore them if you're not interested, but since these games earn some money for their authors they are often of higher quality than the free flash games. It is also very easy to add them to the arcade so there will probably be more of these games being added than others. I don't expect these to be a major revenue source, maybe just a couple bucks a month- they were mainly installed because of easy integration with the new arcade software.
