Business Application of First-Mover Advantage
First-mover in new geographic markets captures network effects before competitors scale. Airbnb entered Europe 2010-2012, local competitors launched 2012-2014 (too late - Airbnb already had critical mass). Google+ launched 2011 when Facebook had 500M users - network effects insurmountable. If competitors already migrated 5+ years ago with network effects lock-in, migration likely fails.
