Black Friday 2010

Later on, the fact that this marked the official start of the shopping season led to controversy. In 1939, retail shops would have liked to have a longer shopping season, but no store wanted to break with tradition and be the one to start advertising before Thanksgiving. President Franklin D. Roosevelt moved the date for Thanksgiving one week earlier, leading to much anger by the public who wound up having to change holiday plans. Some even refused the change, resulting in the U.S. citizens celebrating Thanksgiving on two separate days. Some started referring to the change as Franksgiving.
Advertising tip sites
Some websites offer information about day after thanksgiving specials up to a month in advance. The text listings of items and prices are usually accompanied by pictures of the actual ad circulars. These are either leaked by insiders or intentionally released by large retailers to give consumers insight and allow them time to plan.
