Flash games are easily a multi-Billion dollar a year industry.  You mention games shifting towards Steam.  I&#x27;m pretty sure that there are a lot of games on Steam that are still created in Flash.  Flash (through Air sdk) provides an amazing way to target web and all major mobile platforms with the same code base.<p>Also, I wouldn&#x27;t judge popularity by money made through ads.  The industry has long since shifted to in app purchases.
