433 - 477, [3] pp. Television article, pages 439 - 444. Journal illustrated throughout, primarily with b/w photographic images. 8vo. Television, as we know it, came about in the 1920s. "Scottish inventor John Logie Baird demonstrated the world's first color transmission on 3 July 1928 . Baird also made the world's first color broadcast on 4 February 1938, sending a mechanically scanned 120-line image from Baird's Crystal Palace studios to a projection screen at London's Dominion Theatre. Mechanically scanned color television was also demonstrated by Bell Laboratories in June 1929 using three complete systems of photoelectric cells, amplifiers, glow-tubes, and color filters, with a series of mirrors to superimpose the red, green, and blue images into one full color image." It is this latter feat that is discussed by Ives in this 1929 article, a very early piece on color television. Light wear & soiling to wrappers. Prior owner name inked in top margin of the front cover. A VG+ copy. Original publisher's prined light orange paper wrappers, stapled. Now housed in a clear archival mylar sleeve.
