Many companies use numbers in their branding. Examples are Baskin Robins (31), Seven & I Holdings Co. of Japan. (7-11), Boeing (Boeing 747), Apple (Iphone 4), Sony (PS2), Microsoft (Windows 2000), Microsoft (Excel 2010), Auto Bavaria (BMW 3-series) and many more. Government Agencies uses numbers too such as 911 and local code dialing system. Commercial use of numbers are often related to the psychological retention of the numbers. 7-11 for instance would probably remind you that the opening of the stores are 24 hours a day and you can drop in anytime. Or telling you that you will be on a flight using Airbus A380 means that you can tell all your friends about it! Anyway, this is perhaps the smallest 7-11 store that I have ever seen. It can be found in Hong Kong Disneyland.
Are you attracted by BIG, NICE and IMPRESSIVE numbers?
