Sure, "The King" may have left the building for good, but Shure continues to produce microphones that were good enough for Elvis to use. In addition to an arsenal of microphones, the company makes and sells high-end phonograph cartridges, mixers, signal processors, and wireless systems. Shure's devices are sold through authorized dealers in the US, Europe, and Asia. Artist endorsements from contemporary pop icons such as Christina Aguilera and Sheryl Crow continue to play an integral role in Shure's marketing campaign. Sidney Shure began selling radio parts kits in 1925 under the name Shure Radio Company. His heirs still own the company, which was renamed Shure Incorporated in 2000.
