>I don't think I know anyone who ever used MSN Messenger

I did because it had the best quality video chat at the time, before Skype became a thing, but that was probably 15 years ago. My current company used to use it for in-office communication as recently as five years ago when I was first hired. It was an abysmal mess of sending out group chats as individual windows every time someone had a question. For a software company it was really disgraceful.

My company used Yahoo! Messenger for the longest time. Thank goodness for HipChat/Slack.

But MSN had group conversations (as far as I remember), why not simply use those?

Our office was about 20 people at the time. Any time anyone had a question, but didn't know who to direct it to, a new group conversation was initiated with everyone in the office. That was the problem.
