In 1979 Seagate was founded & was the first company to build 5.25-inch hard disc drives for the PC - Wwhile it may have seemed like a minor milestone at the time, today this hard disc drive introduction is regarded as one event that helped fuel the PC revolution. Suddenly, people could access unprecedented amounts of information, which ventually gave rise to the Internet and other developments.for nearly a quarter of a century, Seagate has been developing the technology and manufacturing the products that helped make it all happen - 25 years later, the world runs on information. Every time you access the Internet, use an ATM, watch TV, listen to digital music, enjoy a movie with computer-generated special effects, or use a consumer-electronics device, you access and share large amounts of digital information on disc drives -- the core of Seagate's business.
