How would the development of soda be affected by America being balkanized? My idea is that regional brands of soda get greater prominence as their nation's soft drink of choice. Like Moxie being the prominent soda of choice for New England. I'm placing a butterfly net over the creation of these sodas for simplicity's sake.
Exactly like that, minor nations and those with enough big market the 'big brand' will consolidated and push their brand over other(just like here my country, Postobon was the consolidaiton of three local brand, posada, tobon and Lux, becoming Postobon for flavorued sodas(Apple one from Lux, Kola and other flavour form Posada and Tobon who have pepsi distrubtion rights and Keeping Lux Brand for Soda Water)
So as say before those brand and if they absorb others become the consolidatin of economical story of each nation.
