➦In 1877...Edison invented the phonograph.
While other inventors had produced devices that could record sounds, Edison's phonograph was the first to be able to reproduce the recorded sound. His phonograph originally recorded sound onto a tinfoil sheet phonograph cylinder, and could both record and reproduce sounds. Alexander Graham Bell's Volta Laboratory made several improvements in the 1880s, including the use of wax-coated cardboard cylinders, and a cutting stylus that moved from side to side in a "zig zag" pattern across the record.
In the 1890s, Emile Berliner initiated the transition from phonograph cylinders to flat discs with a spiral groove running from the periphery to near the center. Other improvements were made throughout the years, including modifications to the turntable and its drive system, the stylus or needle, and the sound and equalization systems.
The disc phonograph record was the dominant audio recording format throughout most of the 20th century. From the mid-1980s, phonograph use declined sharply because of the rise of the compact disc and other digital recording formats. While no longer mass-market items, modest numbers of phonographs and phonograph records continue to be produced in the second decade of the 21st century.

Leonard began in the 11 p.m. to midnight slot, and continued working late nights and Sundays at the station until November 27, 1979. He did the 10:30 p.m. to 1:00 a.m. shift following “Cousin” Bruce Morrow and later George Michael. He also gladly handled weekend and fill-in work.
Leonard was the host of "Sneak Preview," a five-minute Monday-through-Saturday evening program on ABC's American Contemporary Radio Network, which featured newly released songs. He stayed at WABC until 1979, before moving to WXLO and WRKS.
