To mark the 25th anniversary of text messages, Sky News has caught up with Neil Papworth - the man who sent the very first one back in 1992.
Hi Neil, how are you?
I'm very well, thank you, how are you?
Congratulations on the text message being 25 years old - how do you feel?
Thanks! I feel old! It's been an entire generation since I sent that message.
Tell us - how old were you when you sent the first text message and what did it say?
I was 22 years old, and it said: "Merry Christmas." I was working as a developer and sent it to a director at Vodafone who was at his office Christmas party.
Did you get a reply?
No! To be fair, there was no way to reply at the time, so I wasn't offended.
How did you come up with the idea?
Text messaging was not my idea or invention, I just happen to be lucky to have sent that first one.
How do you think text messaging changed the world?
Billions of people started using it to exchange quick messages, whereas before they would have had to make a phone call. Of course, it also introduced the danger of them concentrating on their keypad and screen, and not the road or lamppost.
Did it look like text messages do now?
Almost, yes. It was limited to 160 characters, but no one had yet invented text speak (txt spk) or emojis, and you could only send those very first texts from a computer to a phone, not the other way round.
Do you text a lot or use other messaging such as WhatsApp?
I don't use WhatsApp, but I use some of the social media messaging such as Skype and Facebook Messenger. And I still text when I need to get someone an urgent message.
What's been the best text message you've ever received?
I've received so many, I don't remember! The best one I ever sent was announcing the birth of my daughter.
Do you use emojis and text talk?
Not really! I send smileys the old school way, using characters such as colon, dash, close bracket. :-)
What do you think about the number of people texting going down?
It's inevitable, really. Texting's demise has been predicted for at least 10 years, but it took a lot longer than experts thought before usage started dropping. So many people now have data plans, and there's a great deal of choice of online messaging platforms available.
