Before television was invented, tennis balls were white. They would have remained this way if television had not been broadcast on live TV This was because people couldn't see the white tennis balls flying across the screen. So, they were changed to neon green/yellow so that viewers could see them.

How old is the tennis ball hopper?
The term 'tennis ball hopper' is pretty broad, covering a variety of different tennis court equipment. Tennis ball tubes can be used to pick up balls and as a dispenser you hang on the fence. They generally hold about 15-18 balls and are great for individuals who don't hit more than a couple of dozen balls in a session. Another type of tennis ball hopper is a ball basket. You typically use these to pick up balls by pushing the bottom of the basket on the ball and squeezing it into the storage bin. Many of these models allow you to flip the handles so that the basket can be used like a stand that you can easily grab balls out of. Another type of tennis ball hoppers are the ball carts. These look somewhat like grocery carts. You can't use them to pick up balls, but they can hold about 200-350 balls. One model in particular has collapsible legs that allow it to fit in the trunk of a car. Finally, there are the ball mowers. These are designed to quickly gather large numbers of balls into a container. You push them like a lawn mower and the mechanism inside the mower feeds the ball into a storage unit. Some models of mowers can double as stands or allow you to set up the storage unit like a stand.

How much of these kinds of things will be sold?
Tennis balls are very useful for more than just tennis. Old people put them on their walkers, and people throw them to their dogs. But tennis players use them for, well, tennis. I think the biggest market would be rackets and re-stringing them.
