Forrester estimates that 29% of all online retail sales in the US will be transacted on smartphones and tablets by the end of 2014. Media goods (e.g., video, music, books), clothing, and consumer electronics account for the majority of the approximately $86 billion in mobile phone and tablet eCommerce sales, and an additional $28 billion will be sold on these devices in other categories such as travel and food-services/restaurant ordering, which are not part of Forrester's definition of online retail.
