Apple, Inc. - Two of Apple's old logos.
Some, however, are so drastic that the new marques look like they have been created for completely different companies.
Think Coca-Cola — since the 1880s, its logo design has barely evolved. The Coca-Cola logo is ubiquitous and consistent, and it pays off: Coca-Cola is widely regarded as the most recognized brand worldwide.
But logo recognition is clearly not everyone's top priority. It's a leap of faith to conduct a major logo design overhaul, but many big brands are still willing to take the risk, evolving to the point that their new logos look nothing like the originals. Apple, for instance, has evolved through a huge range of different looks.
We've compiled some of the most drastic logo redesigns in brand history. Double-takes guaranteed.
