Firstly, they may not have the control they did two decades ago over content, but also their ease of exposure through the internet has grown exponentially. People who download content illegally would probably never even heard of said album if it weren't for the very medium they are using to download with. I don't think companies are losing much money, just not making as much as they used to. If they want to change that a totally different approach is needed from the ground up.
I know locally companies need to play catch up. For example iTunes is the largest retailer of music in the US, yet there is nothing available here. After being in the UK I'm used to watching movies, buying new abums and catching my favourite series on the iTunes store, I'm do not even own a CD player or Hi-Fi, so theres no way I'm about to trapse down to the store and buy a disk, never mind petrol, traffic, time. It really is Archaic. I download all of my music, movies and tv shows using torrents and will continue permanently until a change is made. Also the model of 'I have this, now pay me' no longer applies. Money needs to be made in less digital means. Concerts, Merchandise, auxiliary things to the main content. I don't believe companies can ever charge what they were before and will always make less money in the future, that chapter is closed and it's time to move on.
