I wanna introduce a company called LEAP Motion. Leap Motion manufacture a device which can be placed in front of computers, this device accurately mimics human hand movement that allows people to do elaborate jobs on their computer from a far distant without touching the mouse. Leap Motion is a very successful company in the market due to excellent marketing strategies. This company attract its customers by the fellowing ways: First of all, they made a fancy advertisement, showing how wonderful this product can be, And then, one year prior to the release of Leap Motion Controller, this company provide “pre-order” to customers who are interested in this product. Customers who are attracted by this product actually can get another 20$ off if they pre-order it. I am the one who pre-order this product and be one of them who first get this product in the world. After I receive this fancy machine 1 mother later, I finally can see this product in BestBuy, FutureShop.
