Everyone I know is voting for Damien, so it's obvious he'll be the greatest president.
Buying iPhones (idea A) is popular, therefore A is the truth and is a fact.
Advertising is a contemporary example of this fallacy. When a company or product claims to be "the #1 product" or "highest selling" in that industry and uses those "facts" to tell us the consumers to buy the product it is completing the fallacy. Advertising sends consistent messages to "buy this to be happy, fun, cool, popular," How many commercials do you watch and not know what the product is until the end? Today's advertisements focus on the present and rarely (if ever) look at the future or the past. Advertisements give us the illusion that we can buy happiness and companionship. In reality, they're falsely claiming that their product can bring you these intangible experiences and human desires. Years ago, advertisements focused on the facts and actual qualities of the products rather than the potential outcomes for the buyer.
Those marketing the product will argue it is popular to most, so you should use it too, because it is the best. Not because of what makes it the best. They are only drawing attention to its popularity and not the actual measure of how useful the product is.
