At The Motley Fool, we want to be accountable for our recommendations. Each week, I'll make a CAPScall on my profile in Motley Fool CAPS and highlight my pick in Friday's video. This video series may also include updates on previous calls and related news.

In today's video, I look at recent IPO Millennial Media (NYSE: MM) and how its position as the second largest mobile ad company behind Google (Nasdaq: GOOG) will help the stock cash in on the growing mobile industry. Millennial became an industry leader when it recently passed Apple (Nasdaq: AAPL) in mobile ad sales. Additionally, clients such as Zynga (Nasdaq: ZNGA) create opportunities for the ad firm in the niche market of mobile gaming.
