Nothing about the internet changes the fact that the owner of the copyright in a book, movie or music is the only party that has the right to exploit that material. They can offer an end user a license to access the material for a fee, they can give an end user the right to download and play a movie for their personal use, or they can license a movie chain to play that movie in the cinema. Those rights belong to the owner of the copyright and no-one else has the right to use or access the material unless they have the permission (and paid the fee if required) of the rights holder.
