History
In 1982, Sony produced the industry's first portable CD player, the D-50 also called the 'Discman'. This CD player was released just one year after the introduction of CDs on the market, and soon other companies started to release their own portable devices. One of the major problems with the early portable CD players was something called skipping. Skipping consists of the laser inside the CD player temporarily losing its place on the CD, interrupting playback. In 1993 a solution to this was introduced in the form of Electronic skip protection, which caches a few seconds of audio in memory to reduce disruption from mechanical disturbance of the laser.

Famous quotes containing the word history:
“What has history to do with me? Mine is the first and only world! I want to report how I find the world. What others have told me about the world is a very small and incidental part of my experience. I have to judge the world, to measure things.”
—Ludwig Wittgenstein (1889–1951)
“There are two great unknown forces to-day, electricity and woman, but men can reckon much better on electricity than they can on woman.”
—Josephine K. Henry, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 15, by Susan B. Anthony and Ida Husted Harper (1902)
“Every library should try to be complete on something, if it were only the history of pinheads.”
