In today's video, Tamara looks at the fast-growing mobile gaming industry. With the global gaming market on track to reach $17 billion in sales by 2015, there are massive opportunities for investors. However, not everyone can stomach the risks inherent in speculative names such as Zynga (Nasdaq: ZNGA). A safer way to play in this space is by investing in the platform providers.

Companies such as Apple (Nasdaq: AAPL), Facebook (Nasdaq: FB), and Google (Nasdaq: GOOG) take up to 30% of the app sales as well as in-game purchases processed by Zynga and others in the space. Apple's a big winner here, with more than 30 billion application downloads and upwards of $5 billion in payments to developers. This revenue share has been a significant source of income for Facebook as well, with Zynga accounting for 12% of the social network's total revenue.
