Re: Why are films not included in this ruling?
Read the film credits rather than rushing out to be first to the bar. Such items are usually noted there.
Buy the way, films tend to be blatantly commercial products, or did you think they are all done gratis, for the public good?
Also, never, ever credit (or discredit) others with the same experience, education (in)ability or ideas as yourself. You may be a clever clogs who spends the whole film remarking upon the product placements. The rest of us just watch the story and a few, without the benefit of your supreme intellect, may be fooled.
