> As the author mentions, the original moniker for Excel was VisiCalc

VisiCalc wasn't actually a moniker for Excel. It was a predecessor. It was the first spreadsheet program, which was made by a different company, VisiCorp, and released in 1979. Excel was developed by Microsoft and released in 1985. Prior to Excel, Microsoft had released an earlier spreadsheet called Multiplan in 1982.

True. Also Excel was a clone of Lotus 1-2-3, not VisiCalc, as it copied its macro language too.
