Lotus Notes and Lotus Domino were a juggernaut in mid-1990s IT. Some people loved it. Most people put up with it. And then people quit talking about it and thinking about it, even though almost every large organization still has Notes running somewhere. But what is Lotus Notes, and why did it fade from consciousness?
Lotus Notes was a popular software platform for e-mail, calendaring and collaboration in the 1990s. It was programmable and extensible, so many Notes shops created custom applications with it that became business critical. IBM bought it in 1995 for $3.5 billion, but couldn’t keep up with Microsoft’s marketing and the ecosystem that built up around it so it lost market share to Exchange. IBM sold Notes and Domino, its server component, in 2018 to Indian firm HCL for $1.8 billion.
