Factories Scroll Bar

Does anyone know what the bar above each choice in Factories means?

There's a progress bar that shows up above each choice (MP3, pretzels, etc) and I'm not sure if it fills up each time I do each selection.

That's right. The more you produce an item, the bar fills up and then you get a key. The bar then resets until you fill it up again and you get another key. Each key gives you a special bonus like coins, experience, game money and the fourth key will also give you a bonus property.
