History

Other World Computing was founded in 1988 by Larry O'Connor in Woodstock, Illinois. The company initially focused on providing upgrades and accessories for Apple Macintosh computers, a market that was underserved at the time. OWC quickly gained a reputation for offering high-quality memory upgrades and storage solutions that allowed users to extend the life of their Macs. In the 1990s and 2000s, OWC expanded its product line to include external hard drives, optical drives, and later solid-state drives. The company became an authorized reseller of Apple products and other brands, while continuing to develop its own branded offerings. OWC's Mercury line of storage products became popular among creative professionals who needed reliable, high-capacity storage for video editing and other demanding tasks. With the transition to Thunderbolt and USB-C connectivity, OWC was among the first to market with compatible docks and storage solutions. The company also introduced the OWC Envoy series of portable SSDs, which were designed to be compatible with Apple's proprietary storage modules. In 2019, OWC acquired the Akitio brand, a manufacturer of Thunderbolt and USB storage solutions, further expanding its product portfolio. Throughout its history, OWC has remained privately held and has not pursued public listing. The company continues to operate from its Woodstock headquarters and sells its products globally through its website and authorized resellers. It has maintained a strong presence in the Mac community through sponsorships, trade shows, and online forums.
