As Twitter Grows Up, Its Users Don’t

Mobile Commerce Sales Top $10 Billion in First Half of 2013, comScore Estimates

Commerce transactions in the U.S. on smartphones and tablets totaled $10.6 billion in the first half of this year, according to a comScore estimate announced Tuesday. Commerce purchases made on mobile phones accounted for $6.7 billion, while those on tablets totaled $3.9 billion. It’s important to note, however, that there are about twice as many smartphone users in the U.S. as tablet users. Additionally, the $10.6 billion total still accounts for less than 10 percent of total digital commerce sales, though the first iPhone was released just six years ago. Mobile payments — or purchases made in brick-and-mortar stores using mobile devices — are not included in this estimate.
