日本放送
On October 1, 1966, Nippon Broadcasting System, Inc. opened a new record label division, called as Nippon Broadcasting System Service, Inc., in order to produce and market music from Japanese artists. The division formally changed its name in 1970 to Pony Inc. in order to match the brand names it had been using previously. These were "PONYPak" for 8-track cassettes from 1967, and "PONY" for cassettes from 1968.
