Alan Cooper has written about the early history of Visual Basic and how it came to be [1]. Two things i always find interesting was that in his original prototype he didn't use a language at all, but instead used arrows between controls to connect events with methods (i remember seen something similar in an ancient version of Smalltalk for Windows 3.1 that i found in a magazine cover disk back in the 90s) and that in the original version after Microsoft started working on it, it wasn't only the controls that could be extended via DLLs, but also the language itself. Both of those didn't make the cut for VB1, but personally i find them interesting as ideas since they seem to fit well with the overall theme extensibility VB had.
