An example of a backronym as a mnemonic is the Apgar score, used to assess the health of newborn babies. The rating system was devised by and named after Virginia Apgar. Ten years after the initial publication, the backronym APGAR was coined in the US as a mnemonic learning aid: Appearance, Pulse, Grimace, Activity, and Respiration.[6]
Many United States Congress bills have backronyms as their names; examples include the American CARES Act (Coronavirus Aid, Relief, and Economic Security Act) of 2020,[7][8] the USA PATRIOT Act (Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act) of 2001, and the DREAM Act (Development, Relief, and Education for Alien Minors Act).[9] In the 113th Congress (2013) there were over 240 bills with such names.[10]
The Bing name was chosen through focus groups, and Microsoft decided that the name was memorable, short, and easy to spell, and that it would function well as a URL around the world. The word would remind people of the sound made during "the moment of discovery and decision making".[19] Microsoft was assisted by branding consultancy Interbrand in their search for the best name for the new search engine.[20] The name also has strong similarity to the word bingo, which is used to mean that something sought has been found or realized, as is interjected when winning the game Bingo. Microsoft advertising strategist David Webster originally proposed the name "Bang" for the same reasons the name Bing was ultimately chosen (easy to spell, one syllable, and easy to remember).
