Zero Dark Thirty Red Carpet - If you believe about the red carpet, then you probably consider celebrities at film premiers. That's usually the area where red carpets are seen. That wasn't the original intent though. These lengthy, carpet runners actually had a long journey until they got to this elevated condition. The idea of placing a carpet out for important people to walk on probably started in medieval times. Because the roads were virtually non-existent, large puddles and potholes were constantly present in the path of visiting dignitaries and royalty.
A carpet would be put back on the floor so that these vital people would not have to drag their costly clothing through the mud, or worse materials, which could be from the streets. This is basically the same idea as someone putting down their coat to get a princess to walk on. These practices carried on until the roads were substantial enough to negate the need for these practices.
The New York Central Railroad used to put a red carpet on the floor to guide passengers to their right compartments. It is believed that this was the beginning of putting a red carpet for important and famous people. The use of the red carpet in today's society means greater things than in older days. Royalty, celebrities and other VIPs still hope to have one of these carpets rolled out to them at social functions, but now there are more significance to the expression.
The " red carpet treatment" implies that something extra special is being done and many businesses use the term red carpet in their advertising and marketing ploys to increase the perceived value of their services and products. Businesses also use red carpets on the floors in their buildings to make their businesses look more expensive and upscale. Obviously, sometimes this works and sometimes it backfires because so many businesses are employing this method of advertising.
For the most part, if a red carpet is used in a place other than for important people to walk on, then it's viewed as a poor advertising scheme. So now you know how the red carpet came to be. It started with the start of the street and has been around ever since. The idea of red carpets has dwindled to cheap marketing ploys, except if a person is rolled out for VIPs. When used in this way, it's still a major deal.
