In August 1990, Symantec acquired Peter Norton Computing from Peter Norton.[4] Norton and his company developed various applications for DOS, including an antivirus. Symantec continued the development of the acquired technologies, marketed under the name of "Norton", with the tagline "from Symantec". Norton's crossed-arm pose, a registered U.S. trademark, was featured on Norton product packaging.[5] However, his pose later moved to the spine of the packaging, and then disappeared.
