It was founded on October 17, 1987, in response to a severe shortage of surface-mount memory chips in the high-tech marketplace in the 1980s. To provide a solution, Taiwan immigrants John Tu and David Sun put their engineering expertise to work and designed a new single in-line memory module (SIMM) that used readily available, older technology through-hole components. In 1989 It differentiated itself from its competitors with 100-percent testing, which resulted in quality assurance and the leadership position in the market. The following year the company branched out into its first non-memory product line, processor upgrades. The company expanded into networking and storage product lines, and introduced DataTraveler and DataPak portable products. In September 1994, It became ISO 9000 certified on its first assessment attempt. On August 15, 1996 SoftBank Corporation of Japan acquired 80 percent of It for a total of $1.5 billion. In November of the same year, It co-marketed memory upgrades for Toshiba PCs. In 1999, Tu and Sun eventually bought back the 80 percent from Softbank for $450 million. Which Company ?
