A new comScore report reveals that 2011 has been a notably big year for online spending in the U.S. Seven out of the top 10 all-time online spending days occurred in the last month. Taking the top spot is Nov. 28, 2011—a.k.a. Cyber Monday, the digital sister of Black Friday. The date scored $1.25 billion in revenue. But that’s only a small chunk of total spending this holiday season, which, as of Sunday, has reached $24.6 billion—a 15% increase over the same time period last year.
