Black Friday is the day after Thanksgiving and is widely considered the beginning of the holiday shopping season. Here's a look at how the term started and gained popularity across the country through the internet, and from traditional retailers who officially adopted the term as well.

What Does Black Friday Mean?

In the U.S., Thanksgiving Day is the fourth Thursday of November. The next day, Black Friday, is the most popular shopping holiday of the year, with many retailers reserving their deepest discounts and best sales for that specific day.

The name is also connected to the term "in the black," which represents profits in accounting. Many retailers operate at a loss for most of the year (in the red) and make a profit during the holiday shopping season in November and December.

Beginning in 2013 and 2014, more and more retailers began moving back the start time of their Black Friday deals from the early morning hours of Friday morning to the evening of Thanksgiving Day to lengthen the popular shopping day.

Some retailers have gone further, kicking off Black Friday sales as early as the Monday before Thanksgiving Day.

History and Origin

The use of the name Black Friday to refer to the day after Thanksgiving reportedly began in Philadelphia in the 1950s. At the time, police officers in the city used the term internally to reference the large crowds of pedestrians and vehicles that congested Philadelphia's shopping district annually on that day.

The crowds of people and cars resulted in accidents and often violence that required every officer to be on duty to keep order and manage the chaos.

The first published use of Black Friday was in a 1966 advertisement by a rare stamp dealer named Earl Apfelbaum in Philadelphia. However, the term mainly remained regional until the early 2000s, with some increased use in the 1980s in other regions.

Initially, retailers resisted the name because black days of the week have historically described adverse events. A few examples include:

• Black Monday, Oct. 19, 1987: The largest one-day drop in stock market history, when the Dow Jones index dropped 22 percent.
• Black Thursday, Oct. 24, 1929: The stock market crash that is historically considered the start of the Great Depression.
• Black Friday, Sept. 24, 1869: The original Black Friday was the crash of the U.S. gold market. At the time, gold was one of the primary trade markets, with investors from all income levels-most of whom went bankrupt.

Retailers decided to create a new story for Black Friday to shift away from the negative association with the black days of the week.

In accounting, business losses are traditionally recorded in red ink, and profits or gains in black ink. Many retailers would find themselves "in the red" by fall but would be boosted back "into the black" by the holiday shopping season.

To create a more positive association with Black Friday, retailers used this example to explain why Black Friday is called "Black Friday." Eventually, this meaning stuck and is more well-known among shoppers than the 1950s origin of the term.

Online Shopping and Black Friday Deals

The most popular Black Friday deals often center around consumer electronics like TVs, computers, ?tablets, and game systems. While some shoppers are willing to wait in line for hours for a great deal, many prefer to avoid the crowds and shop online instead.

In response, retailers now offer online shoppers many Black Friday deals that kick off simultaneously with the in-store sales. In addition, stores that provide limited-quantity door-buster discounts may offer different door-busters exclusively for online shoppers.

Cyber Monday

The desire to avoid long lines and stampeding crowds paved the way for Cyber Monday. Cyber Monday is the Monday directly following Black Friday and is dedicated to online shoppers, with special deals available as often as every hour on some shopping sites.

Many Cyber Monday deals start even earlier than Black Friday deals, so it's a good idea to shop around and frequently check your favorite online shopping sites for new sales.

Green Monday

Green Monday is the most recent addition to the holiday shopping season set of special deal days. It is the second Monday in December and aims to capture shoppers in stores and online who still have gifts on their list to buy.
