It was in a book that is full of the history of all the car makes in the world. It's a massivly thick book called "Encyclopedia of the Car." I'll quote exactly what it says in the book:
"...although it was largely based on the 1939 TB, the TC helped start a book in sports cars and became something of a cult vehicle. Exports to the United States began early in 1947 and the influence was far-reaching because Detroit entered the same market five years later with the Chevrolet Corvette and, soon after that, the Ford Thunderbird. In fact, the Sports Car Club of America blossomed from one branch of the M.G. Car Club."
