组图：40位40岁以下的商界精英

3. 马克•扎克伯格

•  年龄：29

•  职务：创始人兼CEO

•  任职公司：Facebook

    历时14个月，社交网络Facebook的股票终于在今年夏天超过了首次公开募股时的38美元（现在又涨了）。这是因为，扎克伯格的移动策略似乎终于收到了成效。目前，手机广告销售占Facebook总广告收入的41%，而在最近一个季度，在移动中发布照片和状态更新的人数激增了51%。有消息称Facebook正在计划推出电视广告，单天价格高达250万美元。换句话说，投资者恢复了对Facebook和扎克伯格的信心。

3. Mark Zuckerberg

•  Age:29

•  Title:Founder and CEO

•  Company:Facebook

    It took 14 months, but shares of the social network finally topped their initial public offering price of $38 late this summer (now they're even higher). That's because Zuckerberg's mobile strategy at last appears to be working. Mobile-ad sales now account for 41% of Facebook's total ad revenue, and the number of people posting photos and status updates on the go surged 51% in the most recent quarter. Facebook is also reportedly planning to launch TV-style ads that will cost brands up to $2.5 million a day. In other words, investors' confidence in Facebook—and Zuck—is back.
