Redesigning outdated logos?

I have a class assignment where I have to find a company logo that I think is outdated and redesign with for a fresher look, or to convey its message clearer. So far the only popular logo/company name that I can find that I feel is in need of a new look is the google logo. I think its use of different colored letters are extremely limiting and the font is not modern enough. Does anybody have any suggestions towards redesigning the google logo, or suggestions of other companies in dire need of a new look? any help would be greatly appreciated ;)
