For nearly half of US holiday shopping, phones have become the default device for browsing virtual aisles. And customers this season are buying billions more dollars of products through those devices, according to Adobe Analytics.

Early into Cyber Monday, phones accounted for nearly 60 percent of traffic to online stores and 43 percent of sales -- big increases from last year, Adobe said. Plus, phones drove this year's record-breaking Black Friday, which became the first day ever to reach more than $2 billion in online sales coming from phones.
