Colloquially known as the Tele, this was the world's first commercially successful solid-body electric guitar. Its simple yet effective design and revolutionary sound broke ground and set trends in electric guitar manufacturing and popular music. Introduced for national distribution as the Broadcaster in the autumn of 1950 as a 2-pickup version of its sister model, the single-pickup Esquire, the pair were the first guitars of their kind manufactured on a substantial scale. A trademark conflict with rival manufacturer Gretsch led to the guitar being renamed in 1951. Initially, the Broadcaster name was simply cut off of the labels placed on the guitars (leading to a limited run of nameless guitars known as 'No-casters') and later in 1951, the final name of Telecaster was applied to the guitar. The Telecaster quickly became a popular model and has remained in continuous production since its first incarnation.
