Listerine was a cleaning product until they decided to boost sales by positioning it as a mouthwash.
First, they had to convince everyone that they needed mouthwash, so they invented HALITOSIS (bad breath), and then offered Listerine as the solution.
Lysol tried a similar pivot, except they tried to market their cleaning product as post-sex birth control douche. Listerine's pivot caught on, Lysol's didn't.
