But my point in asking is to quantify how much of their sales and income could be at risk if those same consumers decided they didn't need to be buying products from those companies.
I want to circle back to this.
I'm 67. Atypical in the sense that I consume a fair amount of media that's probably at people aimed 20-30 years younger than me, but still.
So while I'm making coffee this morning, I start looking at the brands around me. Why'd I choose them?
Coffee: Starbucks Breakfast Blend (ground) from the grocery store: I wasn't a coffee drinker before I got married a second time. This was my wife's brand. I just asked how she chose it. Turns out she was at a Bible study maybe 15 years ago, had a cup of coffee, thought it tasted terrific and asked what it was.
Bread: I like dark breads and vary between Oroweat Schwarzwelder Dark Rye, San Luis Sourdough's Dark Rye and Sacramento Baking Company's Native Grain. My wife likes Dave's Killer Bread 21-grain. Never seen an ad for a single one of those.
Butter: Sunnyside Farms with sea salt. It's a California dairy (but most dairy products in the stores here are). For whatever reason, it's two bucks a pound less than Land O'Lakes or Challenge, so I buy it. If the prices were equal, I wouldn't have a preference.
Milk/Half and Half: Again, all from California dairies. I tend to buy whatever has the longest sell-by date.
Preserves: Bonne Maman. Exposed to it in France last year. Not going back to Smucker's or Welch's.
Sodas: Gave 'em up three weeks ago as part of a weight loss effort and don't plan to go back. Was a Coke guy until high school, switched to Pepsi---went back to Coke while in France because it's what most restaurants had, it was made with real sugar, and it was served in a sensible size---300ml (10-ish ounces) bottles.
Ketchup: Heinz. Grew up with it. When (in a restaurant or someone else's house) I had Hunt's or Del Monte, it was too watery.
Mustard: French's, Goulden's and Grey Poupon. Grew up with French's. Exposed to Goulden's at a picnic and Grey Poupon in a restaurant (before the TV ads).
Mayonnaise: Best Foods. Again, grew up with it. I've had others at restaurants, cookouts or whatever and I just prefer it.
Pickles: Clausen's because they're never exposed to heat and there's a really satisfying snap. I remember they had an ad with a stork that sounded like Groucho Marx, but that was after I made my choice (EDIT---I'm wrong. That was Vlasic. Clearly, I wasn't influenced enough to buy their pickles).
Dishwasher soap: Cascade. Maybe I was influenced by the TV ads when I got my first dishwasher in an apartment at age 23...I don't remember.
Liquid dish soap: Dawn. Same deal---might have been those grease-fighting ads. I had to pick something when I got my first place at age 17 and it had hit the market the year before.
Laundry soap: Tide. We both grew up with it.
Too late to make a long story short, but the few purchases we make that were influenced by advertising were influenced when we were in desirable demos.
For major purchases (TV, computers, cars, appliances), I'm going to consult owner experiences, not advertising.
Restaurants, hotels, etc.----Word of mouth (including Yelp, TripAdvisor, etc).
Probably the only thing that advertising influences at our house is movies. We're still big movie fans who enjoy the theater experience. So yeah, we'll see a spot on TV for whatever film and say "that looks good---wanna go?".
I'm open to changing any of those products above---but it would involve me using/tasting it and finding I like it better than what I buy. And advertising isn't going to be what moves me to try it. It would be someone I know, trust, or a discovery that I make away from home.
