The first CD-ROM was invented in 1984 by James T. Russell.
Russell loved music and began getting frustrated at his vinyl phonograph
records when they would get damaged. He also did not like the sound quality
traditional records gave. This was the
start of the development process of the CD-ROM. He wanted a system that could
record and replay sound. The best way he thought to create this idea was to use
light. The first digital-to-optical recording and playback system was successfully
invented in the 1970’s. He continued to perfect his invention and adapt it to
new forms of data. There were a few investors interested in Russell’s work. Eventually
Sony and other audio companies realized the implications and purchased
licenses. In 1985 Russell earned 26 patents for the CD-ROM.
Russell’s invention helped shape our ability to record and
playback music and store files.

The Apple Lisa was the first personal computer to use a
graphic user interface. The Lisa was released on January 1983. It cost Apple
millions of dollars to create the hardware and software used on this computer. Only
about 10,000 units were ever sold. In 1984 Lisa 2 was released with a 3.5"
drive instead of the two 5.25". Lisa 2 was price at about $10,000 dollars
shelf price. A year later Lisa 2 was renamed Macintosh XL. In 1986 Lisa, Lisa 2
and the Macintosh XL line was scrapped. A lot of people say the high price tag,
delays and release date lead to the demise of the Lisa; however, the new
Macintosh did quite well and lead the way to the future of computers.
