Not sure why I searched for this, but it's kind of funny. Do a search for Paypal and they aren't ranked number 1 or even number 2, they come in 3rd. The number 1 spot goes to Paypal Sucks. lol. I wonder if this is due to poor engineering by Bing or if it is due to exceptional SEO by the other guys.
Bing has different search ranking algorithm compared to Google. The #1 website ranking in Google might not ranked same #1 position in Bing.
That's blindingly obvious, but one would expect a company like PayPal to rank at #1 for their own company name. On my system wikipedia comes in at #2, paypalsucks at #6 - the rest are PayPal and their subdomains like "sandbox"
