Here is an answer for your question.
"What Does 'Yahoo' Stand For?"
Answer: Yahoo! (spelled with an exclamation mark) is short for "Yet Another Hierarchical Officious Oracle". This odd and rather long name was coined in 1994 by two electrical engineering PhD candidates at Stanford University: David Filo and Jerry Yang.
The original name: "David's and Jerry's Guide to the World Wide Web", was appropriate, but not exactly catchy. They used the dictionary to come up with “Yahoo!”, a term that anyone can remember and say with ease. More importantly, Jerry and David said they liked the definition of a yahoo: "rude, unsophisticated, uncouth."
In the end, the word Yahoo! did roughly describe it as a web search directory. The term "hierarchical" described how the Yahoo! database was arranged in directory layers. The term "oracle" was intended to mean "source of truth and wisdom". And "officious" described the many office workers who would use the Yahoo! database while surfing from work.

So to answer your question the answer is no. Yahoo is not a Jewish company but it is another search engine like google etc...........
