Editing Format war (section)

==1960s==
*Portable audio formats: [[8-track cartridge|8-track]] and [[Stereo-Pak|four-track]] cartridges vs. [[Compact Cassette]], vs the lesser known [[DC-International]] tape cassette (introduced by [[Grundig]]). While rather successful into the mid-to-late 1970s, the 8-track eventually lost out due to technical limitations, including variable audio quality and inability to be rewound. Similarly the smaller formats of [[microcassette]], developed by [[Olympus Corporation|Olympus]], and [[minicassette]], developed by [[Sony]], were manufactured for applications requiring lower audio fidelity such as [[Dictation machine|dictation]] and [[telephone answering machine]]s.
*[[FM radio]] stereo broadcast formats: The [[Crosby system]] and the [[GE]]/[[Zenith Electronics|Zenith]] system. The Crosby system was technically superior, especially in transmitting clear stereo signals, due to its use of an FM [[subcarrier]] for stereo sound rather than the AM subcarrier employed by GE/Zenith. Many radios built in this period allowed the user to select Crosby or GE/Zenith listening modes. However the Crosby system was incompatible with the more lucrative [[Subsidiary Communications Authority|SCA]] services such as in-store broadcasting and [[background music]]. FM station owners successfully lobbied the [[FCC]] to adopt the GE/Zenith system in 1961, which was SCA-compatible.
