Twenty years since the first text message was sent, texting is now the most popular way to stay in contact, according to Ofcom.
The first ever text was sent on December 3 1992, when Neil Papwell, a 22-year-old British engineer used his computer to send the message "Merry Christmas" to an Orbitel 901 mobile phone.
According to Ofcom, the average person in the UK now sends 50 text messages every week, but younger teenagers send a lot more than this; 12-15-year-olds send an average of 193 texts every week.
Texting has spawned its own entire language of acronyms, which can confuse. The Prime Minister David Cameron's relationship with former editor of the News of the World Rebekah Brooks was revealed after a number of unseen texts between the pair were published.
