A new world of podcasts, newsletters and websites has expanded media in recent years, and provided a lifeline to legacy media refugees who wanted — or were forced to — strike out on their own. Megyn Kelly, Jennifer Rubin, Bari Weiss and Mehdi Hasan are among the barons of this new world with sites like the Contrarian and Zeteo, fueled by the explosive growth of YouTube and Substack in providing a landing place for new ideas. For journalists going on their own, the chance to be their own boss is a plus. Fair warning: experts say to succeed you'll have to work very hard, be adaptable and hope the public doesn't reach a saturation point.
