MapQuest, the once-defunct mapping application, has risen from obscurity to become the number one app in the U.S. App Store, following its refusal to rename Lake Ontario as “Lake America.”

The surge in downloads was triggered by the company’s defiance of President Trump’s executive order, which directed the U.S. geographic naming service to adopt the new name. Google Maps and Apple Maps later capitulated, but MapQuest held its ground, leading to a steady climb in its ranking.

Since the executive order, the app has seen an estimated 632,000 downloads in the U.S. Doug Berger, MapQuest’s GM, highlighted that users are not just installing the app but actively engaging with it, providing feedback and feature requests. The small team is working hard to incorporate these suggestions.

The rapid rise of MapQuest has been impressive, with over 56% of its year-to-date U.S. downloads occurring between August 27 and September 1. This contrasts with its much larger rivals, Google and Apple, who follow official government sources for naming conventions. MapQuest, as a smaller player, has the freedom to take a stand and buck typical conventions.

It’s not the first time MapQuest has taken a stance; it still refers to the Gulf of Mexico by its original name and even offers a playful tool for renaming lakes. MapQuest is now owned by System1, having been acquired from Verizon in 2019, after initially being bought by AOL in 2015.
