Iomega entered the removable storage business in the 1980s with the Bernoulli Box, which could store 10MB or 20MB of data on large magnetic-disk cartridges. Later revisions of this technology yielded the Zip drive (1994), which could store 100MB of data on an inexpensive 3.5-inch disk. People liked the format because it was inexpensive and capacious, and Zip drives enjoyed strong sales throughout the remaining years of the 1990s. But CD-Rs could store even more data (650MB) and when the price of CD-R discs dropped to cents apiece, Zip drive sales plummeted. Iomega tried to keep up with improved drives of 250MB and then 750MB capacity, but the CD-R had already won. Zip faded into history.
