As a kid in the 80s, my parents bought an encyclopedia set that also had a set of companion books for kids. This is where I first learned about a google, and it was definitely google not googol. So it's been "misspelled" for quite some time if that's your belief
Maybe on purpose. Most print encyclopedias included small typos and small fake articles, so they could prove plagiarism if needed. (I use that same excuse to explain all my published errors:-)
