What it is:
The halo effect is a phenomenon whereby consumers perceive the products or services from a certain company to be better than they really are.
How it works/Example:
Let's say Company XYZ makes the "Xphone." The Xphone has many functions and a nice design. Priced higher than the competition, it quickly becomes a status symbol, especially among hipsters and others who are image-conscious.
This group of consumers celebrates the Xphone publicly and even camp out in front of Company XYZ stores to get the latest version, despite the fact that competing devices are less expensive and have the same features. The Xphone is the victim of the halo effect.
