With all the improvements in technology over the years, one such development that has affected education was the release of CD-ROM players for computers. In 1984, seven years after CDs first appeared on the scene, Philips and Sony produced the first. Holding up to 550 megabytes of information, the first CDs used were rarley filled to capacity. In fact, the first educational CD to be released was Grolier's Electronic Encyclopedia which contained 9 million words and used only 12% of the available storage room. With rapid increases in speed, CD-ROM technology eventually began offering applications in additon to large amounts of data. The first educational application on the market was Microsoft's Bookshelf (as if were you really expecting it to come from anyone else). The next major step in CD history was the release of CD-R (recordable CD-ROM) technology in 1991. This technology has filtered into education in a much slower fashion, but does allow for numerous possibilities. The final turn for CD-ROM technology is actually its replacement by the newer DVD technology that provides storage of even larger amounts of data. It appears that CD-ROMs have topped out at 650 megabytes, while DVDs continue to expand since their introduction in 1996.
