The Transatlantic accent, also known as the Mid-Atlantic accent, is a consciously learned accent of English that was popular among the American upper class and entertainment industry in the late 19th and early 20th centuries. It is a mix of American and British English pronunciation, and it was carefully crafted to imitate the upper-crust elite. The accent is characterized by a song-like intonation, lengthily and tremulously uttered vowels, and a booming resonance. It was used in formal public speaking in the United States and was also picked up as the sound of high status in Hollywood. The accent has deep roots in Hollywood history and was used in films and radio programs in the 1930s and 1940s. Although it has disappeared as a standard of high society and high culture, it has still been heard in some media in the second half of the 20th century, or even more recently, for the sake of historical, humorous, or other stylistic reasons. The accent is a mix of American and British characteristics and is halfway between American and British English. It is a hard accent to do and takes plenty of practice. Some people learn it to go into business overseas, while others adopt it for fun or reenactments.
