The FCC approves CBS’s field sequential colour transmission system as the US standard, effective November 20. CBS promises 20 hours of colour programming a week within two months.

Manufacturers are divided as to whether to make sets and converters to receive CBS colourcasts. Meanwhile, RCA works on creating a compatible all electronic colour system.
