The advantages of the laserdisc medium are its stability, quality, extremely fast image retrieval, and density of information on a single disc. Keep in mind that in 1986 when this project began, CD-ROMs were yet to be invented. Today, it would require about 10 CD-ROMs to hold all 54,000 laserdisc images in a compressed JPEG file format. The manufacturers of videodisc players were more numerous in the past. Recently Sony stopped making them even though their Model 2000 was a work horse and continues to keep working even after a decade of use in many libraries.
Sales are still strong, particularly in the interactive training and educational markets.
