Is it hard to work for magazines? How about radio?

I'm thinking of going into journalism. I'm a high schooler and I really enjoy writing and journalim. I know that news papers are dying, but are magazines too? Aren't there so many magazines out there that its not as hard to find a job for one? Also don't they go on the internet too? And is it hard to get into talk radio? Is that really tough to get into?
