consider it this way:
there always were and always will be some people that take some content (music or film or book) for free (library, tv, public concert, lending, radios etc.)
this could have been an immediate loss in some case (exp when one see a bad film or hear a bad song before buying the cd or dvd and decide to not buy it!)
or could be free pubblicity that make a huge profit in the future (for example when young i read tons of book from the public library, now that i have cash i bought many of the best and a lot more from the same autors)
the concept is that some free lunch always existed, and with modern technology it's so easy that there must be some changment in those industries.
that could be draconian DRM to try to maintain an old system that doesn't work anymore....
or could be some kind of restructuring that allow all law abiding citizens of the world to easily and quickly access to all the content they want and pay what they estimate it's worth for them, using the free copies as publicity for theirs product.
decidedly not an easy transition!
and if you think that 90% of the films and songs are propriety of only 3-4 distribution giants you could see where the problem is.
there is only few cartel, not a market were more publicity of your product mean an huger share of the market so that someone could encourage this changeover
