original founders. The Sun name is derived from the initials of the Stanford University Network. Sun was profitable from its first quarter in July 1982. By 1983, Sun was known for producing 68k-based systems with high-quality graphics that were the only computers other than DEC's VAX to run 4.2BSD. It licensed the computer design to other manufacturers, which typically used it to build Multibus-based systems running Unix from UniSoft. Sun's initial public offering was in 1986 under the stock symbol SUNW, for Sun Workstations (later Sun Worldwide). The symbol was changed in 2007 to JAVA; Sun stated that the brand awareness associated with its Java platform better represented the company's current strategy. Sun's logo, which features four interleaved copies of the word sun in the form of a rotationally symmetric ambigram, was designed by professor Vaughan Pratt, also of Stanford. The initial version of the logo was orange and had the sides oriented horizontally and vertically, but it was subsequently rotated to stand on one corner and re-colored purple, and later blue. Dot-com bubble and aftermath During the dot-com bubble, Sun began making more money, with its stock rising as high as $250 per share. It also began spending much more, hiring workers and building itself out. Some of this was because of genuine demand, but much was from web start-up companies anticipating business that would never happen. In 2000, the bubble burst. Sales in Sun's important hardware division went into free-fall as customers closed shop and auctioned high-end servers. Several quarters of steep losses led to executive departures, rounds of layoffs, and other cost cutting. In December 2001, the stock fell to the 1998, pre-bubble level of about $100. It continued to fall, faster than many other technology companies. A year later, it had reached below $10 (a tenth of what it was in 1990), but it eventually bounced back to $20. In mid-2004, Sun closed their Newark, California, factory and consolidated all manufacturing to Hillsboro, Oregon and Linlithgow, Scotland. In 2006, the rest of the Newark campus was put on the market. Post-crash focus In 2004, Sun canceled two major processor projects which emphasized high instruction-level parallelism and operating frequency. Instead, the company chose to concentrate on processors optimized for multi-threading and multiprocessing, such as the UltraSPARC T1 processor (codenamed "Niagara"). The company also announced a collaboration with Fujitsu to use the Japanese company's processor chips in mid-range
