Try again. Search for each and tell us their history.
You said "came out of" ..you didn't say "invented by" ..because FYO, they didn't "invent" search either :)
So if one is going to say "apart from search"..one is obviously not restricting the criteria to only things "invented" by Google..
Words have specific meanings..
Careful use of them, and understanding of semantics helps one rank well in search engines ( even those touched by Ailuropoda melanoleuca ), and avoids some people thinking that one has "seen lights", or had other damascene conversions..:)
They may have "invented" pagerank ..at least they claim to have done so..
