This year, eMarketer expects, 18.8% of all digital ad spending in North America will go toward mobile internet ads—which include all mobile advertising on tablets, smartphones and other devices except messaging-based formats. By 2017, nearly half of all digital ad spending in North America will be on the mobile internet.
Western Europe and Asia-Pacific are nearly tied this year, with 12.6% and 12.3% of all digital spending occurring on mobile, respectively. But Western Europe is expected to expand its share more rapidly, as a relatively mature desktop ad market gives over to mobile channels. Latin America, the Middle East and Africa, and Central and Eastern Europe all have less mature digital ad markets overall, but the direction is clear: A greater share of all digital dollars will go toward mobile each year. By 2017, eMarketer expects, 36.3% of digital ad spending around the world will go toward mobile formats, up from just 4.6% as recently as 2011. Read the rest at eMarketer.
