When I was in high school in the 90's, we had a soda machine that was owned by the school, and had all the different brands - Coke, Pepsi, RC, etc.

One year, they took out the old, independent machines and replaced them with Pepsi machines that were owned by either Pepsi Co or some nameless vendor. They only contained Pepsi brand products - Pepsi, Mountain Dew, etc.

At first we were annoyed, but eventually... I'm now a Pepsi guy for life. I drastically prefer it to Coke or anything else.

At the time, their ad slogan was "The Choice of a New Generation" - And they ensured that by making contracts favorable to school district's bottom lines in a successful attempt to groom me into being a Pepsi guy.

And it worked. I was groomed, and I still abide by my programming to this day, even while being fully aware of it.

If you think you're immune to corporate programming because you're aware of it and are a skeptic at heart - you aren't.
