Ah, but what's the definition of advertising? Probably requires the station to get paid, right? So what happens if the station airs the segment the company produced for free because it lets them be lazy and not hire as many reporters to fill their airtime?
It actually becomes a tough line to draw, because a lot of huge conglomerates own media organizations. If you carry a coronavirus story produced by ABC, do you have to regard it as advertising because ABC is owned by Disney and the virus severely impacts their theme parks?
