Global Online Ad Revenue Share By Company, 2011-2013 [TABLE]

Table - Global Online Ad Revenue Share By Company

Across all digital platforms, Google continues to reign as not only the largest beneficiary of digital ad spending in the US, but worldwide as well, eMarketer estimates. The search giant made $32.73 billion in net digital ad revenues in 2012, equivalent to nearly 31.5% of total worldwide digital ad spending that year. This year, Google will increase revenues faster than the overall market thanks to continued monetization of YouTube and growing adoption of mobile advertising, eMarketer believes, leading to a gain in share of the total digital advertising market.

Facebook came in second in 2012 with $4.28 billion in net digital ad revenues, or 4.11% of the worldwide market. Its share will also grow this year, to 5%. Read the rest at eMarketer.
