Uber was founded in 2009, and pretty broadly available by 2014 Grubhub was founded in 2004, I was ordering from there all through college 2007-2011 Google actually put out hangouts in 2013, and Skype could do group calls in 2010

Not trying to downplay what happened after this: it was incremental change that made the products scale and be more usable to more people. I would say the things you describe as revolutions were actually evolutions of earlier products.
