Question: what is the meaning of 7 up?
Answer: The product, originally named "Bib-Label Lithiated Lemon-Lime Soda", was launched two weeks before the Wall Street Crash of 1929. ... Its name was later shortened to "7 Up Lithiated Lemon Soda" before being further shortened to just "7 Up" by 1936. A myth exists that the 7 Up name comes from the drink having a pH over 7.
