Smartphone and tablet sales and use have increased in recent years, and the latest data on the market for 2011 shows the trend to be continuing.

According to Fierce Mobile, smartphones represented 55 percent of wireless devices sold in the second quarter of this year, and 35 percent of those were sold in the United States. This was the first time the technology passed the 50 percent mark, and Fierce Mobile reported that they accounted for 80 percent of U.S. mobile phone revenue.

This trend may continue to increase over the next few years, for as high school students and young adults become independent consumers, they will put their dollars into the technology already so popular with younger generations. Likewise, as older adults who preferred the standard mobile phones so prevalent in the late 1990s and early 2000s upgrade to the new devices, the smartphone share may continue to rise.

Mobile phones may not continue to hold the largest share of the device market, however, depending on the future popularity of tablets and the emergence of other new technologies. As television and other entertainment media move further toward web-based services, sales may increase for larger-screened devices.
