The United States got SMS a lot later in the piece than other countries, didn't they? From my experience the opposite of what you said appeared to be true - what started to kill SMS here was services like MSN messenger and eventually facebook etc afterwards
Not a surprise that Andy Rubin went on to build Android.
Then MSFT was like, OK we bought skype. EVERYONE WILL USE SKYPE.
MSN doesn’t integrate with your FB contacts automatically so not sure it could occupy the same spot.
Then new people I met (online and offline) were all using Skype. This was just right before Smartphones came out.
Then offline people slowly started joining Whatsapp or Facebook groups.
Online people stayed on Skype until Telegram took over a few years ago.
