Oh, and there's another reason for SeaWorld to evolve beyond the whale shows — a reason you don't hear as much about: They're boring.
At least a lot more boring than they used to be.
If you haven't seen one in a few years, you may have memories of trainers riding on whales and being blasted into the air. Those days are long gone.
After Tilikum drowned trainer Dawn Brancheau, the in-water interaction ended. Nowadays, it's 25 minutes of whales splashing in the tank while trainers stand on dry land, dancing in wetsuits and throwing out dead fish.
