Released in 1987, OS/2 seriously suffered from lack of device support, especially printer and display drivers. The Joint Development Agreement signed between IBM and Microsoft could not prevent the rift between the two companies from growing. The disagreements between IBM and Microsoft led to a situation where each thought it would be better off without the other and the famous divorce ensued. After the divorce, Microsoft almost immediately started pretending that OS/2 never existed, even though the OS/2 subsystem existed in Windows NT until version 5.0 in 1999.
