Just found this:
https://www.thetimes.co.uk/article/e...n%20the%20site.
In there it says that Zuckerburg is credited with creating it in 1996, if that is true then based on what Robin said, Microsoft would be the actual inventor and Robin woudl be one of the original implementers.
I go with Robin on this.
Edited in: I believe after Robin posted his story he corrected himself and moved the date to 1995, not 100% sure on that. The data I am looking at is cut off on the particular post.
