More Facebook Shares to Hit the Market, Including 41.35M From Zuckerberg (AllFacebook)
Another 70 million Facebook shares will hit the market at the close of trade today, as the social network announced an underwritten registered public offering of class-A common stock, with 27 million coming from the company itself and another 43 million from certain stockholders, including 41.35 million from co-founder and CEO Mark Zuckerberg. WSJ Zuckerberg will likely pocket about $1 billion from his first stock sale since Facebook’s initial public offering. Wired Zuckerberg is using a majority of the proceeds from his sale to pay taxes on a separate stock option conversion in which he will acquire 60 million more shares, and he also plans to donate stock valued at roughly $1 billion to charity. Facebook will use its stock proceeds “for working capital and other general corporate purposes.” NYT While the sale will only slightly loosen Zuckerberg’s control on the company, he will still control more than 60 percent of the voting rights. Forbes If early market activity is any indication, existing Facebook investors aren’t rushing to hit the “like” button on the news: shares of the social media giant fell 4 percent in pre-market trading after the announcement.

How Much Mobile Ad Spending Did Facebook Account for in 2013? (AllFacebook)
U.S. mobile ad spending is projected to reach nearly $9.6 billion in 2013, accounting for 22.5 percent of digital ad investments. And Facebook was one of the primary drivers, according to the latest report from eMarketer. CNET Facebook shot past most of its competitors to follow Google in ad sales. EMarketer reports the social media site is expected to sell $3.17 billion in ad dollars this year and points to the general growth of mobile as the source of Facebook’s rise. Bloomberg While Facebook will take in 7.4 percent of U.S. digital-ad spending this year, Google will account for $17 billion, or 40 percent. Listed fourth behind Google, Yahoo and Microsoft in 2012, Facebook is stepping up its ad efforts, generating half of revenue from mobile and testing video promotions that play automatically in users’ news feeds. Instagram, which Facebook bought for more than $700 million last year, is also rolling out ads on its photo-sharing service.
