The Shasta Soda Pop Compnay began life in 1889 as the 'Shasta Water Co.' They bottled, of course, mineral water. Their first foray into sugared water was 'Pale Dry Ginger Ale', first produced in 1931.
It was Shasta who first offered drinks in cans (then steel or tin, now aluminium), and the first compnay to offer 'diet' version of its product.
They are only of only two soda companies in North America that offer drinks in 3-litre bottles.

...and for a while in my youth I know they produced, for a short time, a concotion called 'Chocolate Soda'. It wasn't popular for obvious reasons.
