I get your point but do you think that massive brands like McDonalds would take this path to show you a hidden ads about their brand. no. They can pay millions to blast you their McDonalds cups on TV ads. When these kind of companies want to start to put ads on a new media they have 6 or 7 figures budget. They don't give a damn about paying a 100USD gig to have their McDonalds cups's post on the front page for 3 hours. They want their McDonalds cups on the front page ALL the time.
