I was in the newspaper!

That's right, the speech I gave last week was in the Gakunan Asahi this week. Did you see it?

I was IN the newspaper. You use IN for newspapers and other print media.

I was not ON the Internet.

I wasn't ON TV, either.

Why is it IN for newspapers and magazines but ON for the Internet and TV? I'm not really sure. It's just something you have to get used to!
