The Reston, Va., research firm says sales on six individual days during the first 39 days of the November-to-December shopping season have exceeded $1 billion, led by Cyber Monday, the Monday after Thanksgiving.
"As we enter what will be the heaviest week of the season for online retailers - beginning with `Green Monday' on Dec. 12 - all signs are now pointing to a strong finish to the season," comScore Chairman Gian Fulgoni said.
Over the past six years, "Green Monday" - traditionally the second Monday of December - has consistently ranked among the top spending days of the season.
