Red carpet treatment

References to red as the colour of sovereignty and nobility and red floor coverings being put out for royalty, date back to Ancient Greek times. It is generally acknowledged, however, that the expression red carpet treatment, as it is known today, dates from the early 20th century in America. In 1902, the New York Central Railroad put out plush crimson red carpets to welcome distinguished guests aboard their trains and ever since, the practice has continued to mark important occasions, not just in America, but all around the world.
