Welcome Seaworld Entertainment Red Carpet - If you think of the red carpet, then you probably consider celebrities at movie premiers. That is typically the place where red rugs are seen. That wasn't the first intent though. These lengthy, carpet runners really had a long trip until they got to this elevated condition. The idea of putting a rug out for significant people to walk on probably began in medieval times. Since the roads were nearly non-existent, big puddles and potholes were constantly present in the path of visiting dignitaries and royalty.
A rug would be placed down on the ground so that these important people would not need to haul their costly clothing through the mud, or worse stuff, which might be from the roads. This is basically the exact same idea as someone putting down their coat for a princess to walk on. These practices carried on until the roads were substantial enough to negate the need for such practices.
The New York Central Railroad used to put a red rug on the floor to guide passengers to their pockets. It is thought that this was the start of putting a red rug for significant and famous people. The usage of the red carpet in the modern society means greater things than lately. Royalty, celebrities and other VIPs still hope to have one of those carpets rolled out for them at social functions, but currently there are more meanings to the expression.
The " red carpet treatment" implies that something extra special is being done and many businesses use the term red rug in their advertising and marketing ploys to boost the perceived value of their products and services. Businesses also use red rugs on the floors in their own buildings to make their businesses seem more expensive and upscale. Of course, sometimes this works and sometimes it backfires because so many companies are using this method of advertising.
For the most part, if a red rug is employed in a place other than for significant 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 began with the start of the road and has existed ever since. Now the concept of red carpets has dwindled to cheap marketing ploys, except when a person is rolled out for VIPs. When used in this way, it's still a major deal.
