The US holiday shopping season started even earlier Thursday, as more than a dozen major retailers opened on the Thanksgiving holiday despite protests from workers.
The holiday openings are a break with tradition. The day after Thanksgiving, called Black Friday, had been considered the official start to the holiday shopping season and the biggest shopping day of the year.
But in the past few years, retailers have pushed opening times into Thanksgiving night. They've also pushed up discounting that used to be reserved for Black Friday into early November.
Sales on Thanksgiving were $810 million last year, an increase of 55 per cent from the previous year as more stores opened on the holiday, according to Chicago research firm ShopperTrak. But sales dropped 1.8 per cent to $11.2 billion on Black Friday, though it still was the biggest shopping day last year.
Wal-Mart has been the biggest target for worker protests against holiday hours. Most of the company's stores are open 24 hours, but the retailer was starting its sales events at 6 p.m. Thursday, two hours earlier than last year.
