NEW YORK (November 25, 2012)--Black Friday and Small Business Saturday are behind us and up next is Cyber Monday.

The term, coined in 2005 by a shopping trade group that noticed a spike in online sales on the Monday after Thanksgiving when people returned to their work computers, is the next in a line of days that stores are counting on to jump-start the holiday shopping season.

This year's Cyber Monday is expected to be the biggest online shopping day of the year for the third year in a row.

The research firm comScore says Americans are expected to spend $1.5 billion, up from $1.25 billion last year on Cyber Monday, as retailers ramp up deals to get shoppers to click on their websites.
