I love spreadsheets. A lot, actually. I am a believer that just about anything can be done using a spreadsheet. That is why for me personally, today's "Tech Rewind" is worth sharing.
On July 6, 1995, IBM purchased Lotus Development, the company most known for their Lotus 1-2-3 spreadsheet program. At the time, Microsoft was rapidly grabbing marketshare with Excel, so IBM's purchase was an attempt to keep their dominance in the workplace. Well, it didn't work, as Excel (and really the whole Office suite) got more and more popular. Lotus 1-2-3 just couldn't keep up, and eventually, in 2013, IBM officially stopped supporting 1-2-3.
Lotus Notes (the other main product of Lotus Development that IBM got in the deal 22 years ago) fared a little better over time. Even though Microsoft Exchange remains as a more popular choice in corporate America, Lotus Notes, which is now called IBM Notes, is still around and used at many big corporations.
