What is copyright infringement?

It's essentially just a law that discourages people from using content that they didn't create, which is why you won't hear too many Beyonce songs in the background of youtubers' videos.

An absolute pain in the ass.

Basically it is that you can't monetize property that does not belong to you / that you did not create and when you try to claim it as your own original work.

However this 'copyright infringement' deal is very much abused sa pamamagitan ng content owners that aren't aware of the fair use act (i.e. for educational purposes).

There is a big grey area regarding copyright. Think about artists that create fanart. That there is a huge grey area of copyright. Technically it is the artist's own work, however they are using intellectual property that is not theirs. It's pretty stupid and overly complicated.

Another grey area is AMVs (animated music videos). That is a huge passion of mine, and despite me putting hours into creating my own idea of a music video, they often get a copyright infringement stamp on it due to the music, so all money that video now makes goes to the musician. I think that in those cases it should be some sort of percentage split in profits. It is unfair that all profits go to the person that did not make the original video, however it is a good idea that profits are split to the creator of the music.

This is also why you see your favourite youtubers not using popular songs in their videos. They use what is called royalty free music so they don't get a copyright infringement notice.

Stealing someone's litrato like you did just now.
