Blanket monopoly

What is it with the baby blankets they use in hospitals? Every single child I've ever encountered has come home in the same blanket: white with teal and pink stripes. If these are all made by the same company, they seriously have a lock on the hospital-baby-blanket market. Googling for about two minutes, I can find nine photos of new babies in this blanket: 1 2 3 4 5 6 7 8 9. We still have a couple of ours; they're really durable, which surprises me a little.
