Advertising on clothing has also long been used, with T-shirts being extremely popular. At first, T-shirts were used exclusively as undergarments, but as early as the 1930s, they were already used for advertising, with a 1939 The Wizard of Oz promotional shirt being a prized collector's item today.[1] The 1948 United States presidential campaign featured a T-shirt with "Dew It for Dewey", referring to candidate Thomas Dewey, which is now housed in the Smithsonian Institution. T-shirts have since been used to advertise all different kinds of products, services, and political messages.
The newest trend is to have moving pictures on clothing. The first instance of this was done at the 2003 Rugby World Cup, where "Telstra girls" wore T-shirts outfitted with a small television screen and a DVD player, called "TelePAKs".[2] This was duplicated in the United States in 2004 with "Adver-Wear" that made its debut advertising the film I, Robot.[3]
