You still get plenty of commercials on YouTube or on demand services for individual channels.
Not to mention ads in app and on websites.
Does that mean Demolition Man is a work of fiction or a glimpse of our future?
Could be. The "jingles" kids heard on TV and radio back in my day...don't seem to be as prominent on ads in general.
I it even a problem if nobody remembers commercial songs, I can't see a problem.
