Once. And the hosts thoroughly embarrassed me.

Twice in Australia. I won a P!nk CD.

A local station interviewed my brother and I went with. They let me answer the phone for questions and say a few words. It was pretty cool.

I talk to the news talk station in Toronto sometimes (News talk 1010) just to give in my input o3o

I was, once
But it was a local thing and it was about some old monument xD

When I was 11, I entered a Radio Disney contest for an electric guitar! (But I lost D

Otherwise, no. I WAS on TV because our school was the trial for some new program to teach kids about alternate energies, but that's about it.

I was just on TV and in the newspaper.

Not live, but the song I performed was. So I guess it kinda counts.

When I was around 7 or 8, my mom drove me to a very small radio station that was near the bakery she use to work. It was a spanish radio station, and it was my brother's birfday so I decided to wish him a happy birfday over the radio... and I was forced to sing the song too. OTL;
