The Two Versions Of Thrush

In The Man From UNCLE TV series:

a woman who appeared in a single episode claimed to have founded Thrush and was not contradicted;

Thrush was not an acronym.

Thus, within the TV series, these have to be accepted as the facts of Thrush.

However:

David McDaniel's carefully crafted and ingenious account does far more justice to the size and complexity of Thrush;

it is easy to assume that that woman in a single episode was deluded or lying.

Indeed, it is strange that this character and her claim appear only once and therefore are missed by anyone who did not see that particular episode.

On TV, a single Ultimate Computer was constructed and destroyed before it could be used. We may deduce from McDaniel's account that more were built. The UNCLE Chronology which claims that the prototype Ultimate Computer was built in 1898 goes beyond McDaniel's account and fits UNCLE into the expanded Wold Newton universe. However, McDaniel does state that Thrush pioneered information technology. See Thrush History II.
