When were rectangular colour TV sets first on the market?

[Steve D.]

Motorola did lead the rectangular parade with the TS-908 chassis in 1964. It used a 23EGP22 picture tube. Once the engineering bugs were worked out as far as convergence and pin cushioning effect, the rec.tubes were a big hit. bigger screens with better aspect ratio and less depth on the cabinets. Also a better choice of screen sizes, 19-23-25" ect. ment that color sets could be used in rooms other then the living room. This at the very time the networks were expending their color schedules.
