This is an updated version of my previous data visualization video following the usage of IM clients over the years. In this data visualization video I look at the most popular instant messaging apps based on monthly active users. It includes the first graphical instant messaging app, PowWow. It was far ahead of its time but did not gain much traction.

I know there are many more apps but their numbers were either missing, completely off or not high enough to include in the list. Here are the ones I included:
