Do you know the history of spreadsheet?
Spreadsheet has been invented by Dan Bricklin and Bob Frankston. 32 years ago, both had invented great tool for us. First of all, I am thankful to them and all others who have contributed for making today spreadsheet. In interview of Google+'s hangout, Dan Bricklin told that history of spreadsheet is totally connected with business and finance. He is MBA. He had to do big calculations for financial forecasting. For this, he needed a great computer calculator for this. So, we worked on this tool. First spreadsheet was in Ms Dos. Later, Microsoft company has worked on it and made ms excel spreadsheet.

His Reference Idea
The idea for the electronic spreadsheet came to me while I was a student at the Harvard Business School, working on my MBA degree, in the spring of 1978. Sitting in Aldrich Hall, room 108, I would day dream. "Imagine if my calculator had a ball in its back, like a mouse..." (I had seen a mouse previously, I think in a demonstration at a conference by Doug Engelbart, and maybe the Alto). And "...imagine if I had a heads-up display, like in a fighter plane, where I could see the virtual image hanging in the air in front of me. I could just move my mouse/keyboard calculator around on the table, punch in a few numbers, circle them to get a sum, do some calculations, and answer '10% will be fine!'" (10% was always the answer in those days when we couldn't do very complicated calculations...). Read full history of first electronic spreadsheet at Dan's personal website.
