Question: When was the operation system developed jointly by IBM and Microsoft first released? Passage 1:In the world of sports, mascots are also used for merchandising. Team mascots are often related to their respective team nicknames. This is especially true when the team's nickname is something that is a living animal and/or can be made to have humanlike characteristics. For more abstract nicknames, the team may opt to have an unrelated character serve as the mascot. For example, the athletic teams of the University of Alabama are nicknamed the Crimson Tide, while their mascot is an elephant named Big Al. Team mascots may take the form of a logo, person, live animal, inanimate object, or a costumed character, and often appear at team matches and other related events, sports mascots are often used as marketing tools for their teams to children. Since the mid-20th century, costumed characters have provided teams with an opportunity to choose a fantasy creature as their mascot, as is the case with the Philadelphia Phillies' mascot, the Phillie Phanatic, and the Philadelphia Flyers' mascot, Gritty.
 Passage 2:In 1907, Fitzgerald presided over the first trial of Harry K. Thaw, who was accused of murder. Thaw was the mentally unstable heir of a railroad baron, and he had killed a renowned architect, Stanford White, who had previously sexually assaulted Thaw's wife, Evelyn Nesbit, who was a famous fashion model and chorus girl. The trial was the subject of intense public interest and was highly sensationalized in the press, becoming one of the earliest examples of the "trial of the century" phenomenon. Fitzgerald ordered the jury to be sequestered, which was a highly unusual step at the time. In a contemporaneous report, the New York Times could only identify one specific previous case in which this had occurred. Fitzgerald had to declare a mistrial when the jury was unable to agree on a verdict. After a second trial in 1908 (under a different judge) ended with verdict of not guilty by reason of insanity and Thaw was incarcerated in a state hospital for the criminally insane but continued to pursue legal challenges to his incarceration, Fitzgerald suffered a nervous breakdown in 1911 that was attributed to the strain of the trial.
 Passage 3:In November 1988, a new development team within Microsoft (which included former Digital Equipment Corporation developers Dave Cutler and Mark Lucovsky) began work on a revamped version of IBM and Microsoft's OS/2 operating system known as "NT OS/2". NT OS/2 was intended to be a secure, multi-user operating system with POSIX compatibility and a modular, portable kernel with preemptive multitasking and support for multiple processor architectures. However, following the successful release of Windows 3.0, the NT development team decided to rework the project to use an extended 32-bit port of the Windows API known as Win32 instead of those of OS/2. Win32 maintained a similar structure to the Windows APIs (allowing existing Windows applications to easily be ported to the platform), but also supported the capabilities of the existing NT kernel. Following its approval by Microsoft's staff, development continued on what was now Windows NT, the first 32-bit version of Windows. However, IBM objected to the changes, and ultimately continued OS/2 development on its own.
