I still remember my ICQ number. A few people used AOL/AIM, but ICQ was very popular for some time, I had more contacts on ICQ then I ever had on Facebook. Then Microsoft shipped their own Messenger pre-installed on Windows, and people started using Messenger instead. Then came Skype, which replaced the desktop phone. And more and more moved over to Skype. Then there was clients that allowed you to use both AIM, ICQ, Messenger and Skype) finally you could have all your contacts in one place. But Google also wanted to join the game, launched their own G-talk, then bought and shutdown one of the most popular multi-clients... So what should I use at this point? Lets go with Skype. Then Microsoft bough Skype. And kinda crippled it... So people started to use the chat on Facebook... And then the Smartphone market become really huge. So the big players turned their focus on mobile. Opening a void on desktop, which was later filled by Slack...
