When a situation is completely changed by an event, we call the event a game changer. A good example of a game changer is the invention of the internet. In January of 1983, the 14 year old ARPANET changed into the current IP-version of the internet. This event had a massive impact on our ways of thinking and acting. Other events changed the world in a similar way. WhatsApp, Uber, Gorillas and Airbnb all changed big parts of the world when they were first released. What game changer changed your life the most?
