Final answer:
The best example of narrowcasting among the options provided is D. Bleacher Report blog, as it can target very specific sports interests and niches.
Step-by-step explanation:
The term 'narrowcasting' refers to the practice of delivering programming or content to a specific, targeted audience, rather than to a broad, general audience. Narrowcasting usually involves segmenting programming into specialized genres designed to appeal to particular interest groups, enhancing viewer choice and interaction.
Considering the options provided, the best example of narrowcasting would be:
D. Bleacher Report blog
This is because a blog like Bleacher Report can provide content that is focused on very specific sporting interests, teams, or niches within the sports world. This directly contrasts with more general broadcasting options such as:
A. Monday Night Football, which is a regular feature on national television and has a broad target audience.
B. ESPN, which is a sports network aimed at a general audience of sports fans.
C. Chicago Sun Times sports page, which covers a wide range of sports news, mainly for the Chicago area.
