Microsoft

Software giant Microsoft is one of the most prominent companies that uses the Helvetica font. It was not the company's original logo — it switched to an italicized version of the Helvetica font in 1987. The logo, which connects the letters O and S, was created by Scott Baker.

3M

The product design conglomerate 3M considers its logo, which uses the Helvetica font "one of our most valuable company assets, and consistent usage enhances marketplace recognition." Like many other corporations, 3M does not permit its logo to be used outside of set guidelines indicated on its website without company permission.

Panasonic

Japanese electronics producer Panasonic switched the Panasonic brand logo to Helvetica in 1971, 16 years after the brand was introduced in Japan. Two years later the company switched its National brand logo to Helvetica as well, although Technics remained with another font until the other two brands were switched to Panasonic.

General Motors

General Motors, once the largest car company in the world and a stalwart of the American corporate scene, has been using the GM logo in Helvetica since 1964, when the logo was first displayed at the World's Fair.

American Apparel

American Apparel still manufactures its clothing in the U.S. instead of abroad, but like many other corporations it also uses the Helvetica font for its brand. The brand logo can be seen in the company's sometimes controversial advertisements.
