In 2009, 32% of consumers ages 18 and older have accessed the Internet on their mobile phones. This was an 8% increase from 2007, and predictions are that the number of users will only rise.
It is interesting to note that the Internet was not the only aspect of mobile technologies with usage patterns divided by race. In general, Black and Hispanic users utilized every mobile activity at a higher percentage rate than White users.
