Kenjiro Takayanagi is a Japanese engineer who developed the world's first TV set to display the received electric signals on a cathode ray tube on December 25, 1926 although the West, particularly the United States ignored his contribution to the development of all-electric television set. 

It seems obvious that the hatred toward Japan and her people deeply embeded in the U.S. occupation policy has surfaced even in the area of television development after the Greater East Asia War ( read this post "The Greater East Asia War" VS. "The Pacific War" ), as evidenced in the historical fact that General Douglas MacArthur, Supreme Commander for the Allied Powers (SCAP), banned Japan's research on TV during the occupation of Japan.
