Odds of Getting In
Breaking into broadcast journalism isn't exactly hard, per se, but there's a methodology to it. No one, and we mean no one comes out of college and instantly turns into Anderson Cooper.

If you want to be a recognized TV reporter (or at least one who makes more than $38,000 per year), then you have to start small and work your way up. If you live in a big city, you're going to need to downgrade and get into a small town where you can get your feet wet before you can earn your way back to civilization.
It's going to be a tough road and the market is shrinking, so you may want to start hedging your bets by developing other skills.
Is becoming a professional and successful TV reporter doable? Yes. Is it likely you'll become successful and famous along the way? We can't be so staunchly affirmative in answering that one.
