Final answer:
The question seems to pertain to the interconnectedness of professionals in media and the historical evolution of network infrastructures that have shaped modern media consumption.
Step-by-step explanation:
Regarding the question about the writer being part of an 'elaborate network,' this seems to reference how writers, producers, and actors are interconnected within the entertainment industry. Especially in the context of movies such as The Net with Sandra Bullock.
Films like this illustrated concerns about the impact of digital network connections on personal identities at a time of significant technological change. Furthermore, the question about the director's role in casting in theatre versus TV refers to the influence of the Network in television productions.
In the context of history, the development of the ARPANET, a precursor to the modern internet, shows how the evolution of media consumption and communication technologies has grown from basic research networks to complex systems involving satellites, fiber optics, and cellular networks, shifting from text-based to visual and video media. Insights into how networks needed local affiliates for broadcaster access before cable and fiber optics became prevalent highlight the changing infrastructure that supports our current media landscape.
These infrastructural changes also facilitated the rise of the Internet and social media, which have dramatically expanded the choices available for news and information consumption.
