Many studios had both and so could have produced
bin loop masters in either format.. Maybe it was the
player manufacturers who chose Dolby B?

IIRC, Philips only licensed the use of their format if their specification
was adhered to. Anything else would be a nonsense.

Dobly B was not a part of the spec.

The C cassette was launched in 1963 and
Dolby B was first demonstrated five years later
