There's Product Replacement Ads where's the ads are actually put into a movie or show for example, the new James Bond alone was finacially sponsered by Ad company from the car that he drove to the watch that he wore.
A simple one would be regular TV shows where a box of cereal is shown in the show when thirty some years ago it used to be just a blank box labed "cereal".
It's becoming a big fad in the commercial industry because technology is letting the viewers tape and fast forward through the commercials. An example of a piece of tech would be Tebo.
It's bad and good depending on your views. I think that it's good, but I have a line where's it's the limit.
one bad reason is that it sometimes makes the show/movie feel like a long episode of commercials and is like crap
a good reason is that not all product replacement are bad adding in truthful to make people aware of something
Hoped that helped you
