Yahoo! is an American company that started out as a search engine and ended up as sort of a joke. I am telling you right now, if you still have a Yahoo mail account active delete that right now. What once was the master of all search engines is now the diseased prostitute on the corner, over used and out of luck.
The problem really came with a fun service called "Yahoo Answers." The Internet equivalent of Jay Leno's "Jay-walking" sketches, all you have to do is ask a random question and a variety of smartasses and morons will give you an answer. Just read this fun feed for some of the best. My favorite recent one is: "Does rubbing peanut butter on your nipples and butt cheeks prevent demonic possession?" Someone actually tried to answer this!
Still, after all that, they made a pretty funny commercial.
