| Advertising is a weird business. There's different types of media: print, television, digital (banner ads). Print is dead (has been the increasingly accurate argument for 10 years now), television is expensive and untrackable, and digital is here to save the ad industry because that's where all your customers are and it's very trackable. The value to the advertiser is either direct-action ("click here and buuuuuy!") or branding ("we exist, see!") Companies like Verizon, Proctor and Gamble, Johnson and Johnson, unilever, etc. spend billions on branding. How does that money get allocated? Well, you've got a brand manager for, say, Acme Inc. Their job is "Get more people to buy" and they split their resources between creative--often working with big agencies (think Madmen, see AdAge)--and media buying. There's often pressure to spend less on creative and more on ad buys. And when ad buys don't perform, they say "We should have spent more on creative". Media buying is basically buying banner ads (or tv or whatever). They're typically sold at a CPM (Cost Per thousand iMpressions), less often Cost Per Click. So to answer your question: major brands have billions for branding and it's a bunch of people's jobs to spend that money and convince the people they work for that it's money well spent. And if it's not money well spent, they'll find someone who will tell them it is. |
I'll be the first to say there's a lot of mismanagement, incompetence, politics, etc that leads to this but it's also one of the most data driven industries around and there's a lot of proof behind the results. It's not all just random guessing.
