Here's a (link) to a list of the 100 most-loved companies, according to a survey done by APCO Insight.
The research company uses "emotional linking" data to come up with its list, which includes admiration, approachability and relevance a consumer has for a company. Topping the list was Walt Disney, Yahoo! and Google.
I wasn't surprised with Disney being at the top, but Yahoo! was an interesting second choice. It did well in the understanding (knowing what the company does) and approachability categories.
