Los Angeles Times: The first text message was sent out on Dec. 3 1992. Engineer Neil Papworth wrote "Merry Christmas" on his computer and sent it to Vodafone director Richard Jarvis.
Since that time, of course, text messaging has changed quite a bit. We've gone from T9 predictive text messaging, to full QWERTY keyboard devices such as BlackBerrys, touchscreen smartphones and most recently, we can tell our voice-dictation services such as Siri to write our messages for us.
Text messaging has also gone mainstream, from being an activity exclusive to teens and young adults to becoming an essential way to communicate for many older adults.
