When Google appeared on the search engine market there was virtually nothing. People who were using HotBot were considered geek and into computers.
Search was a big business, for sure, but it wasn’t like a whole slew of large search engine companies was out there.
Search was mostly an also done. You had a portal or a whole family of sites — and search. Don’t really need search as you already offer what anyone would ever need, right? Anyway, let’s slap it on there. Bam. Search. Thanks.
