Black and white

Black and white (B/W or B&amp;W) images combine black and white in a continuous spectrum, producing a range of shades of gray. In the 1910s through 1950s, all to some movies were made only in black and white.
The earliest television broadcasts were transmitted in black and white, and received and displayed by black and white only television sets. Scottish inventor John Logie Baird demonstrated the world's first color television transmission on July 3, 1928.
