Reilly made his strong comments at the Hollywood Radio and TV Society's State of Broadcast panel, according to Variety.
"We don't spend enough time thinking of the consumer in the chain, we think about the audience in a clump," he said.
"If you ask execs how they watch TV, they're either not watching a particular product or they just watched five seasons on Netflix. So, why is [this exec] any different than anyone at home?"
Reilly claimed that network bosses are "way too obsessed with one another and not with the consumer" and argued that networks should rethink how they schedule shows following a "massive shift" in viewers' behaviour with the advent of online streaming and DVRs.
Earlier this year, Reilly defended the Fox network's disappointing performance in this year's Emmy nominations, with the broadcaster managing just 26 award nominations, substantially fewer than those of rival channels CBS (60), NBC (51) and ABC (48).
"Seminal shows like House and 24 have cycled out," he said in July. "Next year we will have some [more]."
Reilly has also billed forthcoming Kevin Bacon Fox drama The Following as "the next 24", praising the horror thriller's "highly serialised" format.
