<P> The Goodyear Blimp is any one of a fleet of airships operated by the Goodyear Tire and Rubber Company, used mainly for advertising and capturing aerial views of live sporting events for television . The term blimp itself is defined as a non-rigid airship--without any internal structure, the pressure of lifting gas contained within the airship envelope maintains the vessel's shape . </P> <P> From the launch of the Pilgrim in 1925 to the decommissioning of the Spirit of Innovation in 2017, Goodyear generally owned and operated non-rigid airships in its global public relations fleet . In 2014, however, Goodyear began a process of replacing its three U.S. non-rigid airships (blimps) with three new semi-rigid airships, each of which will have a rigid internal frame . Although technically incorrect, Goodyear has planned to use "blimp" in reference to these new semi-rigid models . Wingfoot One, the first such model in Goodyear's U.S. fleet, was christened on August 23, 2014, near the company's world headquarters in Akron, Ohio . </P>
