(CNN) -- This Monday is dubbed "Cyber Monday" because U.S. "e-tailers" traditionally unveil special promotions on this day. U.S. stores enjoyed big crowds on Black Friday, so called because it is when retailers are said to move out of the red (operating at a loss) and into the black as the holiday shopping season begins.

Total holiday-related buying on the Internet is also forecast to jump 24 percent, to more than $24 billion.
$457.4 billion -- Amount the NRF estimates will be the total spend in the U.S. this holiday season -- a growth rate of five percent on the previous year's figure, but slower than last year's 6.1 percent increase.
140 million -- Estimated number of U.S. shoppers that hit stores on Black Friday weekend.
