Ernst & Young, commonly known as EY, is one of the world’s most respected professional services firms, established in 1989 through the merger of two pioneering firms: Arthur Young & Co., founded in 1906, and Ernst & Whinney, founded in 1903. With a global footprint spanning over 150 countries and 700 offices, EY employs more than 270,000 professionals. The firm specializes in audit, tax, legal, strategy, and consulting services, making it a key player among the Big Four accounting firms.

In 2013, Ernst & Young underwent a significant rebranding, unveiling a streamlined logo and adopting "EY" as its official name. This move aimed to enhance brand consistency and clarity, reflecting EY's aspiration to lead in its field. The new logo features bold, capitalized "EY" letters paired with the tagline "Building a better working world." A vibrant yellow triangle complements the minimalist design, injecting energy and modernity into the visual identity.

The rebranding, while strategic, received mixed reviews. Critics like Business Insider ranked the redesign as one of the worst corporate logo changes of 2013, comparing it to a design for a tech startup or logistics company. Despite the backlash, EY defended the update as a step toward solidifying its reputation and reflecting its ambitious vision.

The font choice in the updated logo prioritizes simplicity and legibility compared to the earlier italicized typeface. Overall, the 2013 redesign marks a shift from a traditional professional services image to a modern, accessible identity.
