Final answer:
If MacNeil were to lead network programming, he could make changes to incorporate riskier and more innovative shows that challenge authority and offer original content to attract viewers.
Step-by-step explanation:
If MacNeil were in charge of programming for a network, the changes he might make would likely involve taking more risks with show selection. His approach could involve seeking out programs that are unusual and potentially risky, much like how the Fox network decided to air The Simpsons, which became a hugely successful series with a strong political message about questioning figures of authority.
MacNeil might place emphasis on innovative content that doesn't necessarily conform to traditional or mainstream expectations but has the potential to draw in viewers with its originality. This strategy is often employed by channels looking to boost their ratings by differentiating themselves from competitors. By endorsing creative freedom and opening the door to more diverse programming, MacNeil's leadership could lead to a network that offers a fresh slate of shows that challenge viewers and encourage critical thinking.
