=== VHS development ===
In 1971, JVC engineers Yuma Shiraishi and Shizuo Takano put together a team to develop a VTR for consumers.<ref>{{cite news|url=https://www.nytimes.com/1992/01/20/world/shizuo-takano-68-an-engineer-who-developed-vhs-recorders.html |title=Shizuo Takano, 68, an Engineer Who Developed VHS Recorders |work=The New York Times |date=January 20, 1992 |access-date=2011-07-11 |first=Andrew |last=Pollack}}</ref>

By the end of 1971, they created an internal diagram, "VHS Development Matrix", which established twelve objectives for JVC's new VTR:<ref name="rickmaybury">{{cite web |url=http://www.rickmaybury.com/Altarcs/homent/he97/vhstoryhtm.htm |title=VHS STORY – Home Taping Comes of Age |publisher=Rickmaybury.com |date=September 7, 1976 |access-date=2011-07-11 |archive-url=https://web.archive.org/web/20110719095527/http://www.rickmaybury.com/Altarcs/homent/he97/vhstoryhtm.htm |archive-date=2011-07-19 |url-status=dead }}</ref>

* The system must be compatible with any ordinary television set.
* Picture quality must be similar to a normal air broadcast.
* The tape must have at least a two-hour recording capacity.
* Tapes must be interchangeable between machines.
* The overall system should be versatile, meaning it can be scaled and expanded, such as connecting a video camera, or dubbing between two recorders.
* Recorders should be affordable, easy to operate, and have low maintenance costs.
* Recorders must be capable of being produced in high volume, their parts must be interchangeable, and they must be easy to service.

In early 1972, the commercial video recording industry in Japan took a financial hit. JVC cut its budgets and restructured its video division, shelving the VHS project. However, despite the lack of funding, Takano and Shiraishi continued to work on the project in secret. By 1973, the two engineers had produced a functional prototype.<ref name="rickmaybury" />
