When were balloons invented?

Believe it or not the Indians of Central and South America made balloons from leather.  However the rubber balloon was invented by Michael Faraday in 1824.  He used it with experiments with hydrogen.  But what fun are rubber balloons if only scientist get to play with them?  It didn't take long before rubber balloons were being sold for a penny a piece at circuses and in parks in America. The latex balloons we're more familiar today were first manufactured by J.G. Ingram in1847 London. Mass productions of latex balloons didn't occur until the 1930s.  It makes me wonder how much more roaring history would tell us the 1920s would have been if mass production had started a decade sooner?
