Broadcast and cable networks are breaking the rules for news coverage of a presidential campaign. No other candidate could just call on the phone and get on the air to hold forth before details of the terror attacks in Belgium had been reported. Donald Trump has received almost $2 billion worth of free media coverage, building audience share and driving ad revenue through the roof. No presidential candidate has received so much free time as the former reality star – and he is almost never called to account. Broadcast executives are unapologetic about the advantage it gives him over his competition. Is real journalism being sacrificed for the bottom line?
