1928: W3XK, the first American
TV station, begins broadcasting
from suburban Washington,
D.C. The station was an outgrowth
of the work done by Chartles

projected onto a 6-inch-square
mirror to create the picture,
rather than using electronics,
the technology that determined
the future of television.
