Charles P. Ginsburg

1920-1992

Engineer who developed the first practical videotape recorder. Ginsburg was born in San Francisco, California, and graduated from San Jose State in 1948. He worked as a studio and transmitter engineer at a San Francisco radio station before joining the Ampex Corporation in 1952. Ginsburg developed a new method for recording a television signal by using a rapidly rotating recording head to apply high-frequency signals to magnetic tape. Ginsburg led Ampex in the development of a special machine that ran the tape at a lower speed, working in conjunction with the high-speed recording heads. His videotape recorder (VTR) changed the face of television. Networks soon replaced live broadcasts with taped and edited shows.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
