Final answer:
Major television networks avoid showing talking heads for various reasons, including viewer preferences, the rise of talk show hosts and political pundits, and concerns about credibility.
Step-by-step explanation:
Major television networks avoid showing talking heads because of several reasons. Firstly, the rise of cable television and the internet has given viewers more options and control over what they watch. This has led to an inundation of information and viewers becoming more skeptical and fatigued about politics. As a result, networks may prefer to show other forms of content, such as reality television and movies, to cater to viewers' preferences and avoid losing their audience.
Secondly, talk show hosts and political pundits have emerged as alternatives to traditional news anchors. These individuals offer expert opinions and commentary on political issues, often representing partisan or ideological viewpoints. This shift allows networks to provide diverse perspectives and fill the gap left by the decline in viewership of traditional news shows.
Lastly, major news networks may also avoid showing talking heads due to concerns about credibility. When an anchor or pundit loses credibility, it can negatively impact the network's reputation and audience trust. News agencies are aware of this relationship and carefully select anchors to maintain trust. The example of Brian Williams of NBC, who was suspended and later removed from his position, demonstrates the importance of accountability and credibility in the news industry.
