The Gulf of Mexico will now appear as the Gulf of America for U.S. users of Apple Maps, Bing Maps and Google Maps.

Apple Maps and Bing Maps are both joining Google by changing their Maps software and apps to now display Gulf of America on the body of water that's been known as the Gulf of Mexico since the 16th century.

The name change to Gulf of America is the first since the 1540s where various maps referred to it as the Mexican Gulf, Golpho de la Nueva España, and, finally Gulf of Mexico.

Mexico says Google relabeled the entire gulf, including Mexican and Cuban maritime areas, but President Trump’s order applies only to the U.S. continental shelf.

Mexican President Claudia Sheinbaum said the label should only include the waters under US jurisdiction, not the entire gulf.

Mexico is threatening to sue Google over the tech giant's use of President Trump's "Gulf of America" (renamed from Gulf of Mexico) label on its maps. Why it matters: It's the latest fallout over Trump's executive order to rename the body of water.
