Like books maybe?
Im into watching sports.
What's fascinating to me about these people who rose to the top of "leaker" type og journalism is the empire of connections they built to sustain being one of the first to release bomb shell news. Their livelihood depends on being slick with people, building rapport and a sustainable info network.
Other than needing money to bid for some info, You'd still have to be unbelievably entrenched in an industry, like EU soccer leagues or the nba, to become and maintain the go to guy to release info before any other person or big company.
