The abbreviation FYI, commonly understood as "For your information," predates the internet, as evidenced by its use in early media like The Twilight Zone. Similarly, the acronym "lol," often associated with online communication, has historical roots, including its use in medical shorthand to refer to "little old lady" in "no apparent distress." Additionally, the practice of using abbreviations has a long history, dating back to 19th-century Morse code telegraphy, which utilized contractions for efficiency. This trend continues today with airport recognition symbols and stock market tickers that feature corporate abbreviations.
