They're kidding, right?
Has anyone on these forums heard of Digital Rights Management? That's what media companies first did to combat piracy.
Now that they know DRM isn't working, they're lobbying governments to rewrite the laws in their favor.
Of course they're changing, into multimedia developers (however ineffectively). They are also downsizing, fast. And they're trying to work together, for the first time, to control prices set by Amazon.
Anyone who thinks media companies aren't changing is simply not paying attention.
