IBM didn't take the microcomputer seriously, until it saw how well Apple did and then made an IBM PC to compete with it. They made a deal with Microsoft for DOS, but didn't make the deal exclusive so Microsoft sold their own version of DOS to the PC Cloners. IBM made the PS/2 series with Microchannel as Clone Killers. VGA was a better video, and Creative Labs had the Sound Blaster for better audio. IBM's Microchannel flopped because people wanted to still use their ISA cards. IBM had OS/2 and Microsoft had their own version of OS/2 and Windows, and Microsoft took their OS/2 NT 3.0 and made Windows NT 3.1 out of it and stabbed IBM in the back for a second time. IBM sold their printer line to Lexmark, and their PC X86/X64 line to Lenovo, IBM didn't know how to turn a profit on them. When IBM couldn't supply the PowerPC chips to Apple for their Macintosh line, because IBM was making PowerPC chips for video game consoles as a priority, Apple switched to Intel chips. Then later video game consoles switched to Intel or AMD chips. IBM open sourced their PowerPC chips eventually. IBM bought out Lotus and basically ran it into the ground and let Excel replace Lotus 123, and Lotus Smartsuite was never updated to compete with Microsoft Office and for modern Windows systems so it fell away and IBM forked OpenOffice.Org to make Lotus Symphony. That also went nowhere. IBM still earns money from mainframes and contract support. I think IBM got into Linux and Java contracting as well. But IBM has changed over the decades and it is not the same company it once was. It fell into a trap of maximizing shareholder values rather than making the customer experience a better one like Apple did. Microsoft also suffers from the same sort of thing that IBM does which explains why Microsoft Surface sales tanked. IBM needs a big reboot, and to focus on making the customer experience better. Mobile apps is an area they could focus on, make the IBM Cloud and then make IBM Lotus Symphony for iOS and Android and store the documents on the IBM Cloud and offer subscriptions for more storage. They should also make Lotus Domino and Lotus Notes for mobile devices, and make a set of developer tools to make Android and iOS apps easier to program.
