Inexpensive reel-to-reel tape recorders were widely used for voice recording in the home and in schools, along with dedicated models expressly made for business dictation, before the Philips compact cassette, introduced in 1963, gradually took over. Cassettes eventually displaced reel-to-reel recorders for consumer use. However, the narrow tracks and slow recording speeds used in cassettes compromised fidelity. Ampex produced pre-recorded reel-to-reel tapes for consumers of popular and classical music from the mid-1950s to the mid-'70s, as did Columbia House from 1960 to 1984.
