2 2 af 21 Timeline 1884 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 Paul Nipkow sends images over wires using a rotating metal disk technology calling it the electric telescope with 18 lines of resolution.

3 3 af 21 Timeline 1884 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 John Baird's 30 line images were the first demonstrations of television by reflected light rather than back-lit silhouettes. Recording of dancing girls.

5 5 af 21 Timeline 1884 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 The Russian inventor, Vladimir Zworykin invented the cathode-ray-tube called the kinescope in 1929. The kinescope tube was sorely needed for television.

6 6 af 21 Vladimir Zworykin developed an even better camera tube called the Vidicon. Timeline 1884 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 Vladimir Zworykin developed a camera tube called the Orthicon. The Orthicon had enough light sensitivity to record outdoor events at night.

7 7 af 21 Timeline 1884 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 AT&T launches Telstar, the first satellite to carry TV broadcasts - broadcasts are now internationally relayed. First MOS transistor build at Bell Labs. Bobeck and his team demonstrates magnetic bubble memory at Bell Labs.

8 8 af 21 Timeline 1884 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 Boyle and Smith invents the Charge Coupled Device CCD.

9 9 af 21 The fractional quantum Hall effect. Timeline 1884 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 Nobel avards to Bell Labs Ivan Stensgaard employed at Bell The wave nature of matterThe transistor The electronic structure of glass and magnetic materials The Cosmic microwave radiation The cooling and trapping of atoms The CCD sensor

10 10 af 21 The CCD principle Boyle and Smith got inspiration from the Metal Oxide Semiconductor structure (MOS). And from the Magnetic Bubble Memory.
