Origin and history of extended

extended(adj.)

mid-15c., "occupying time, made longer," past-participle adjective from extend (v.). Meaning "stretched out" in space is from 1550s; extended-play (adj.), in reference to recordings (especially 7-inch, 45 rpm vinyl records) is from 1953; in reference to pinball games by 1943.

A challenging question was asked RCA engineers and scientists in 1951. How can we increase the playing time of a 7-inch record, without using a larger disc? Sixteen months of research gave the answer, "45 EP"—Extended Play. [Radio Corporation of America magazine advertisement, May 1953]

 Extended family (n.) in sociology is attested by 1907.

Family.—This term should be limited to the group consisting of parents and children. The term 'extended family' may be used for a group of persons descended from the same grandfather or grandmother or more distant progenitor .... [W.H.R. Rivers, M.D., "Some Sociological Definitions," Report of the British Association for the Advancement of Science, 1908]
