Internet, not Innernet, you crazy Americans!

Is it just me or do all Americans pronounce the Internet innernet. I hear it over the radio/TV/youtube everywhere, am I missing something here? is the T silent? this upsets me because at times I wonder if there is another Internet named Innernet, are there two different giant networks? one that I’ve never visited before? is the internet as I know it just a layer in a multiverse like multinet?

It would be great if someone could clear this up for me.
