1895 – The Lumiere brothers showed their first film to an audience. It was a romantic comedy about a crowd of mostly women leaving a building.

1960Frickin’s Laser Beams Patented
             The first patent on a laser is issued to Arthur Leonard Schawlow and Charles Hard Townes, who assign it to Bell Telephone Laboratories. Still, no one has figured out how to attach these “lasers” to the heads of sharks. Throw me a frickin’bone here!

1981RCA Selectavision Videodisc
             The first vinyl video record, a.k.a the videodisc, hit stores in the U.S. The “Capacitance Electronic Disc” looked just like any other vinyl record protected in a plastic caddy and held 60 minutes of NTSC video. That is approximately 27,000 frames per second.
However, the CED players did not make the impact RCA had hoped. Only 100,000 were sold by the end of the year. The “BetaMax vs. VHS” war was in full swing and the tapes were considerably smaller than the discs. Laserdisc was also available to the public, which led to a lot of confusion of formats.
The RCA Selectavision was retired in 1984 with the last discs released in 1986.

1993Intel Begins Shipping “Pentium” Chip
             Intel announces it is shipping its Pentium microprocessor. Engineers Federico Faggin, Ted Hoff, Stan Mazor, and Masatoshi Shima, an engineer from the Japanese firm of Busicom, invented the world’s first commercial microprocessor at Intel in 1971 – the Intel 4004.

2016 – Sony began taking orders for its Playstation VR headset. The first pre-orders were for a $499 bundle including the headset as well as Move controllers and a camera.
