Did you know Apple owes its success to VisiCalc, the first computer spreadsheet system? Conceived and designed by Dan Bricklin in 1979, spreadsheets have revolutionised business computing.
In this TED Talk, Dan talks about how he came up with the idea and executed it. How having a multi-disciplinary background aids innovation. There are some great pictures of the technology they used. Even if you’re not particularly interested in computers, I think you’ll marvel at just how far we’ve since those early years.
