Records have changed size and shape through the years. The cylinder-shaped phonograph record for use with the early Edison models was made about 1889. Disc records were first made by 1894, the double-sided disc by 1904. High-fidelity records were first issued in 1944, the first vinyl disc in 1946, the first stereo record in 1958. The 78 RPM became the standard in 1926 but was discontinued in 1957. In 1932, the first 33 1/3 RPM was made but was not sold commercially until 1948. In 1949, the 45 RPM was introduced. Compact discs became available in the U.S. in 1982 and many companies began phasing out the production of phonograph records. All types of records are collected if the music or musician is famous.
