If I remember correctly "carbonated" drinks have been around longer than that - but the carbonation was achieved through using yeast instead of infusing with CO2. Also the the drinks usually had a small alcohol content, but usually not much (like 0.5 to 1%).
Well, this sounds like homework. And I am not going to do it all for you. But I will give you a link that answers all of your questions in the "History" section. Here's the link: http://funadvice.com/r/14jo45cpcbp :)
Carbonated drinks were first invested when an Englishman named Joseph Priestley discovered a method of infusing water with carbon dioxide in 1767. So... since 1767. Hope this helped! :)
Oh wait, it's probably not homework seeing as though your are 22 years old... but oh well. The link tells you everything you need to know. :)
Do you know what the reason was for inventing it? And also do you know when it was drank by the general population?
Lol. He is just curious. It isn't homework. I lolled though.
Since the late 17th century
