APPLE
This is a company keeps everything very secretive until the very end. For example when opening a new store they don't tell the location or time of the opening until just a week before. This makes costumers very curios and they talk about rumors and it becomes free advertisement for Apple. And the opening becomes like an event. There are lines of people waiting outside starting about 24 hours before the opening and then the whole staff comes out excited and encouraging. Also, every time someone buys an app, apple gets 30 % of the profit and they also get money for any advertising shown on the app.
MICROSOFT

SONY
