    Television was actually invented long before the technology to make it a reality came into being. As early as 1876 Boston civil servant George Carey was thinking about complete television systems and in 1877 he put forward drawings for what he called a "selenium camera" that would allow people to "see by electricity."

    Electronic television - based on the cathode ray tube work done independently in 1907 by English inventor A.A. Campbell-Swinton and Russian scientist Boris Rosing.

    American Charles Jenkins and Scotsman John Baird followed the mechanical model while Philo Farnsworth, working independently in San Francisco, and Russian émigré Vladimir Zworkin, working for Westinghouse and later RCA, advanced the electronic model.

    Jenkins, in the U.S., and Baird, in England, got the 1st television programming on the air in the 1920's, even if all they initially broadcast were stick figures and silhouettes.

    Sony introduces the first in its "Watchman" series of handheld, battery-operated, transistorized television sets. Model FD-210, with its 1.75-inch screen, is the latest entry in a 30-year competition among manufacturers to produce tiny micro-televisions.

  • FCC sets a testing schedule for proposed all-digital HDTV system

    Following a demonstration by Philips two years earlier of a high-definition TV (HDTV) system for satellite transmission, the Federal Communications Commission sets a testing schedule for a proposed all-digital HDTV system.
