The internet is kinda cool, don't you think?
It can be cool, because it is the global system of interconnected networks throughout the world!
Was Al Gore really the inventor? 
I don't think so. The origins of the internet actually date back to research commissioned in the 1960's. 
That was a long time ago. Is any person credited with inventing it?
I think so, but I'm not sure of the names. The early 1990s marked the beginning of transitioning into the modern Internet.
