when did the records take over the production of the phonographs
Phonograph The use of a flat recording surface instead of a cylindrical one was an obvious alternative which thought-experimenter Charles Cros initially favored and which practical experimenter Thomas Edison and others actually tested in the late 1870s and early 1880s. The oldest surviving example is a copper electrotype of a recording cut into a wax disc in 1881. The commercialization of sound recording technology was initially aimed at use for business correspondence and transcription into writing, in which the cylindrical form offered certain advantages, the storage of large numbers of records seemed unlikely, and the ease of producing multiple copies was not a consideration.
Music recording certification At the industry level, in 1958 the Recording Industry Association of America introduced its gold record award program for records of any kind, albums or singles, which achieved one million dollars in retail sales. These sales were restricted to U.S.-based record companies and did not include exports to other countries.[3][4] For albums in 1968, this would mean shipping approximately 250,000 units; for singles the number would be higher due to their lower retail price.[4] The platinum certification was introduced in 1976 for the sale of one million units, album or single, with the gold certification redefined to mean sales of 500,000 units, album or single. No album was certified platinum prior to this year. For instance, the recording by Van Cliburn of the Tchaikovsky Piano Concerto from 1958 would eventually be awarded a platinum citation, but this would not happen until two decades after its release. In 1999, the diamond certification was introduced for sales of ten million units.
