Search for colleges or universities who offer journalism, mass communication and broadcasting schools. Since competition is keen in broadcast journalism, chances of starting off as a news anchor are rather slim.
Journalists should have thorough grounds in liberal arts (i.e. history, humanities, english). For preparation in broadcast journalism, take courses like introduction to mass media, basic reporting and copy editing, news writing, history of journalism, journalism ethics, public speaking, graphics and layout, political communication, and desktop-publishing.
Video, audio and lighting production courses would help out a lot, too. (Final Cut Pro)
Journalists should be up-to-date with current events, and have a sense to communicate well in English. Superior writing skills, that is.
Taking courses related to the Internet like web page design, computer-assisted reporting would help out as well; media is transitioning into online media.
I was told that internships, when you do graduate from a college or university, would help a student fresh out of college to compete for broadcasting jobs.
