I always thought that scaring people is not a good marketing strategy but I'm probably wrong then.
When something was scary during your childhood it leaves a mark on you and that thing probably still remains scary!
In my case is true, never had a good feeling about television, now I remember, when I was a little child (3/4 years old) I was afraid of fixed images on the screen and I was like 'in a minute something bad or scary will happen' and there was an advertising (more like a memorial or something) after the 11/9/2001 including a fixed frame at the end of it with a big pause symbol ( I I ) resembling the twin towers, I was 7 years old back then and I was still afraid of that.
Seems stupid but thinking about those memories are still making me nervous now.
I mostly use the tv as a screen for my PS3 but eventually it will happen to see one of those new advertising you were talking about, and this will scare the 🤬 out of me.
Luckly italian advertising are getting dumber and dumber, involving stupid jokes or fake crappy superheroes/monsters/robots to convince the children. Never thought it was a good thing, but I'm ok with that then!
