The Aiken tube was the first flat CRT from about 1958. It was sold in very limited numbers for military use, but it was never commercialized.

The Sony FD 200 was sold in Japan, January, 1982, 6 months ahead of the FD 210 for the American market. These two models were the first commercialized true flat black and white CRT's.
The ED 15 CRT used in these two models was an incredible 5/8 inch thick and the only true flat CRT. All later Sony Watchman sets had a slightly curved screen and were slightly thicker because of the curvature.
