What characterized the changes in television formats during the post-network era?

The post-network era in television, which emerged with the rise of cable and streaming services, saw a significant transformation in how content was produced and consumed. The correct answer highlights the trend of rebranding popular network formats as a way to attract and retain audiences in an increasingly competitive media landscape.

As networks and streaming services sought to differentiate their offerings and build strong viewer loyalty, they adapted existing formats that had proven successful. This involved introducing popular game shows, reality programs, or serialized dramas, but with new twists or thematic updates to reflect contemporary culture and audience interests. This strategy enabled platforms to capitalize on already established viewer preferences while also innovating to meet the expectations of modern audiences.

In contrast, the other choices do not accurately reflect the dominant trends of this era. The return to traditional broadcast formats is more aligned with earlier television history prior to the diversification of viewing options. The complete rejection of advertising is not supported by the reality that many platforms still rely on ad revenue, especially free streaming services. Lastly, while sports programming remains popular, it is not the defining characteristic of the post-network era, which is more about the variety and adaptation of existing formats across multiple platforms.
