If your special interest is television journalism, many local cable stations have public access, volunteer programs. These can give you some excellent experience in all areas of television production experience which is invaluable whether your dream job is in front of the cameras or behind the scenes. Extracurricular activities, volunteer experiences and internships. Internships provide hands-on experience in far more depth than is possible in even the most intensive college course. Enter your completed projects in student competitions.
Many professional competitions have special student categories.
Anyway, I have to admit that I don't have all the answers or that sure-fire formula for success. You could ask a thousand reporters and anchors how they got started in the business, and you'd probably hear a thousand different stories. But one thing they almost surely have in common is persistence. Don't be shy about using the connections you've made on internships, volunteering, and so forth. Use it for filler once you get an interview.
