This is the story of Improv. Another time where Steve Jobs was shown a revolutionary new application. This was the first application that implemented the equivalent of pivot tables.
To quote the Linux Spreadsheet page:
" I would suggest that what happened in the history of the developments is that, for ``political'' reasons, the developments attributable to Lotus Improv (originally developed using NeXtstep ) were lost, and that its better model of spreadsheet construction/management was thereby lost."
