How many products claim to be number one?

Answer 1

Many, many products claim to be number one, preferred, best, most loved, most powerful, most popular, etc. The ability of companies to advertise products this way has been tested in courts in the United States and elsewhere. When the statement is a matter of opinion, personal taste, or judgement, a certain amount of hyperbole is accepted. When the statement makes a very specific, verifiable claim about a product ("#1 selling truck four years in a row" or "proven to cure Diabetes permanently") that statement must be defensible. Sometimes the statement that a product is number one will have an explanation or limitation presented when the statement is made ("#1 selling fuel efficient car*" might have "*of all American four-door four-cylinder gasoline engine cars in 2008" elsewhere on the page).
