Final answer:
The tendency of the media to focus on content that attracts large audiences for profit maximization is known as commercial bias. Narrowcasting, on the other hand, involves targeting media content to specific niche audiences.
Step-by-step explanation:
The tendency of the media to make coverage and programming decisions based on what will attract a large audience and maximize profits is known as commercial bias. This concept refers to the media's prioritization of content that is appealing to viewers and advantageous for advertisers, which often leads to the avoidance of complex social and political issues that might alienate certain audience segments or advertisers. As a result, media companies often follow the viewing patterns established by the audience to maximize profits for their investors.
In contrast, narrowcasting refers to media outlets targeting content toward specific, niche audiences rather than attempting to appeal to the mass market. This approach has become more prevalent with the rise of cable television and the Internet, enabling viewers to select programming that aligns with their personal interests.
