When Ray Kroc flew over towns looking for church steeples to open McDonalds stores
Ray Kroc in the 1940s owned a successful Milkshake mixer distribution business. In the beginning of 1950s his business started to slow down. In the US there was an exodus from the cities to the suburbs and many neighborhood soda fountains were forced to close down. But one small restaurant in San Bernadino kept ordering more machines. He flew down and met the McDonald brothers who ran the restaurant.
When Ray Kroc joined the McDonald brothers, he envisaged thousands of Mc Donalds outlets across the country. In trying to identify the best locations, he used to fly over towns looking for church steeples. He believed that good American families would live around churches and that's the kind of customers he was looking for.
