Mobile Ad Spending in 2007 to Double to $1.5 billion

Just in case the trend toward mobile advertising wasn’t already clear, InfoWorld hits all the major reasons why we’re headed for a huge increase in spending. They point to a study by Informa Telecoms & Media, which projects that spending will reach $1.5 billion this year, and $11 billion by 2011. Although some prior adventures in mobile ads have failed, one failure they highlight — Spotcast Communications, in Hong Kong — occurred in 1999, before phones were capable of properly displaying ads, much less showing content that people wanted to see.
