The below logo was used on the first "Subway" location created. It was owned by the chain's founder Peter Buck and thus he called the restaurant "*Pete's Subway" (with the asterisk included). One of the founders was Fred Deluca.
This logo was also used in some commercials from 2002–2003 and 2015-present alongside with the 2002–2016 logo, and a 2015-present Subway commercials.
Starting in January 2002, Subway started using a modified version of the logo. By early 2003, all branches had the new look. In this logo, the oval behind the wordmark was removed. The slogan used with this logo was "Eat Fresh.". As of 2016, this logo is still used as a secondary logo. This logo is still used in many locations.
On December 28, 2015, Subway introduced a new green-colored version of its current logo and a new slogan "Founded on Fresh," which was later changed to "Fresh is what we do." This logo is still used in all colors. This logo was-short lived.
On August 5, 2016 Subway introduced a new logo inspired by the 1968 design. The new logo is slated to go live nationwide in early 2017.
