Cyber Monday sales in the United States reached $2.29 billion, a 16 per cent increase year-on-year, according to the Adobe Digital Index 2013 online shopping data.

The data showed a record of 18.3 per cent of sales came from mobile devices, an increase of 80 per cent year-on-year.

This traction stemmed from the country’s Thanksgiving Day and Black Friday sales, which recorded online sales of 1.062 billion and 1.93 billion, respectively. For the first time more than 24 per cent of online sales occurred on smartphones and tablets, a record increase of 118 per cent year-over-year.

According to Adobe, while ‘brick and click’ retailers dominated Thanksgiving weekend sales, internet retailers generated the most sales on Cyber Monday with a 42 per cent share.

“Retailers earned ten per cent of their holiday sales in just the last five days, an increase of 26 per cent year-on-year,” said Tamara Gaffney, principal analyst of Adobe Digital Index.

“Sales from mobile devices saw the biggest gains with an 80 per cent increase over last year.”

The analysis also showed tablets and game consoles were the main contenders of the day with iPad generating the most social media buzz of any tablet followed by the Samsung Galaxy tablet. PlayStation 4 was the leader in social media traffic on game consoles over the last five days.

Adobe’s online shopping data is based on the analysis of nearly 900 million visits to 2000 retailers’ websites on Cyber Monday and more than three billion visits since Thanksgiving Day.
