More than two-thirds -- or 68% -- of U.S. adults have a smartphone, up from 35% in 2011. Plus, the share of Americans who own a tablet computer has risen by a factor of 10, and today, 45% of U.S. adults own a tablet.

That's all per a new Pew Research Center report.

At the same time that smartphone ownership is on the rise, computer ownership is falling, especially with the younger generations.

In 2010, 88% of Americans under the age of 30 owned laptops, but that number has fallen to 78% in 2015. Eighty-six percent of Americans in the same age bracket own smartphones.

Ownership of tablets has increased dramatically since 2010, but it is statistically the same as it was in 2014, at 45% -- which corroborates other reports of tablet sales slowing down and reaching a saturation point in the U.S.

e-Readers and mp3 players have both lost share in the market since 2010.

Pew researchers conducted telephone interviews from March 17 through April 12, 2015 among a national sample of 1,907 adults over the age of 18.

Separately, mobile is also ascending to a dominant position in the Third World. In India, a state that is decidedly mobile-first, marketers are predicting a shift in mobile marketing efforts that coincides with the saturation of mobile devices among the general population. Location-based marketing and mobile wallets will be among the most used technologies by marketers, with 88% and 70% of marketers utilizing them by 2020, respectively.

As the U.S. becomes more mobile-centric in its approach to information and entertainment, analysts expect to see a similar shift in tactics.
