On September 1, 2015, Google changed their primary logo and overhauled their identity package.
If you missed what they said on the topic, I recommend reading it here.
There are countless articles, blogs, essays, tweets, etc. on the topic (everyone has an opinion about everything). So I'll stick to two quick thoughts.
1) As a communications professional, I think it's a brilliant piece of work, and their explanation/rationale is well done.
2) It reminds me that beyond the insular world of marketing, design, advertising, whatever-you-want-to-call it, logos don't really matter all that much.
A new logo won't change how many people use Google for search. It won't change how they think of the company. It won't make them uninstall an app (or install one faster) on their favorite device.
It's just a logo. People have already decided what the "brand" means to them. Me? I'm a fan.
Even if I prefer "googol" as the spelling.
