It’s been a bumper season for online shopping in the US. After Thanksgiving Day and Black Friday saw record-breaking online sales, Cyber Monday has also chalked up a record $2.29 billion in online sales, according to data from Adobe Digital Index 2013.

Cyber Monday becomes the fifth day in a row of record-breaking online sales, Adobe says. In all, total online sales for Thanksgiving through Cyber Monday jumped 26 percent year-on-year to $7.4 billion — which according to principal analyst Tamara Gaffney, is 10 percent of retailers’ annual sales.

Online sales for Cyber Monday posted a 16 percent on-year rise to $2.29 billion — and a record 18.3 percent of sales were made via mobile devices, up a whopping 80 percent from the year earlier.

In total, smartphones and tablets accounted for $419 million of sales on Cyber Monday, with tablets driving the majority of mobile sales, making up 12.7 percent of the total online sales. The most popular mobile device that consumers used for mobile shopping was the iPad — which took 10.1 percent of total online sales. Android-based tablets generated $23 million or one percent of total sales.

Social media played a part in promoting the wave of online shopping throughout the five days, driving $148 million in online sales between Thanksgiving and Cyber Monday, but Adobe notes that its 2 percent share of total sales is flat from last year. However, Twitter’s share grew most — up 24 percent to make up 9 percent of total online sales. Facebook drove 64 percent of all social media-driven sales, an increase of 12 percent.

While traditional “brick-and-click” retailers outsold their “online-only” competitors during Thanksgiving, the latter generated the most sales on Cyber Monday with a 42 percent share, Adobe notes.

Adobe’s online shopping data is based on the analysis of nearly 900 million visits to 2,000 retailers’ websites on Cyber Monday and more than three billion visits since Thanksgiving Day.
