Subway unveils its new logo featured on top of its original logo.

Subway is doing something it hasn't done in more than a decade. It's changing its logo.

The sandwich shop revealed on Friday that it's ditching its bulky, outlined lettering in favor of a more simplified, clean design.

"We see this as a way to refresh our look while remaining true to the brand's roots by using the vibrant color palette of the mid '60s when we were founded," a spokeswoman from Subway told CNBC.



The new lettering retains elements of the previous design such as the iconic arrows, which the company says symbolize the choices Subway provides its guests. This is the sixth time in the company's 50-year history that the sandwich chain has altered its logo.
