Manufactured Sensation

When a company pays people to advertise a product by singing its praises in highly unlikely situations. The attempt is to make the product look more important than it actually is. In reality, people can see though the lie and tend to hate the company for it.

Subway has a commercial featuring a bunch of people singing about it's $5 foot long subs. This is a "Manufactured Sensation" because no one in their right mind would gather a church quire to sing about sandwich.
