(CBS News) NEW YORK - One day after the holiday season kickoff, the nation's merchants have reason for joy. By one estimate, the number of Black Friday shoppers was up 20 percent over the same day last year. The question now is whether shoppers can maintain the pace.

It's shaping up to be a record setting opening to this holiday shopping season. Wal-Mart, the nation's biggest retailer, says it sold nearly 5,000 items a second on Thanksgiving night as stores opened their doors this year earlier than ever.
