Cyber Monday sales broke a record in 2013, with shopping on mobile devices leading the charge.
Purchases made on mobile devices surged 55.4% year-over-year, and made up 17% of Monday's total online sales, according to IBM's e-commerce report.
Smartphones were more popular for making purchases than Tablets, said IBM.
This is in stark contrast to Black Friday sales, which fell 13.2% from the prior year, according to ShopperTrak, a retail industry firm. But that's partly because many retailers, including Toys 'R' Us, WalMart (, )Target ( and )Best Buy (, opened their doors on Thanksgiving Thursday, cutting into the traditional Black Friday sales. )
ShopperTrak said sales for Black Weekend, which spans Thanksgiving Day through Sunday, crept up 1% compared to last year.
"Black Friday shopping is no longer a one-day event," the firm said in a press release.
