We all think like home theater buffs and audiophiles. There are people - I don't know many personally, but I know there are a lot of them - who will listen to .mp3s through earbuds, and think they hear music. These people are reshaping the music industry. One of my daughter's friends looked at my CD collection, and looked at me in something like shock. "You *buy* music? Music is *free*."
Movie execs, I promise you, are watching this in terror. There are plenty of people - the equivalent of mp3 listeners - who will happily watch a movie at lo-res from 5 inches away, if it saves them $3 on the cost of the movie. Better still if it can also be upsampled, however poorly, for their TV sets. As things are *today*, downloaded movies will eventually clobber DVD sales, just the way .mp3s are hurting high end audio. Any higher availability of digital content will make it worse.
The other point to consider is that people here are complaining about movie companies making "enough" money, so that they could afford to cut their profits a little. This is nonsense. The decision makers at companies draw some irrelevant salary, but the real and only story is their stock. The value of their stock is what matters and ALL that matters. And if it's forcasted that their company's profits are going to go down - at all - the stock price falls. The owners lose personally AND they get sued by investors, because these days "financial responsibility" is legally defined as "guaranteed continued returns on investment". That's right, boys and girls, you can land in court if your company's value proposition goes down and anyone can prove it was your fault.
So companies don't innovate much anymore. Innovation is risky and risk doesn't carry guarateed returns. Result: companies go to court, buy politicians and do anything they can to preserve an existing business model, no matter how outmoded by new technology, illegal, or stupid it may be. Embrace change? That's 1950s economic thinking. It's a lot safer to buy laws that protect what you have.
*Sigh*
