Review Questions

• How does broadcast television differ from cable and satellite television in terms of accessibility and delivery methods?
  • Broadcast television differs from cable and satellite television primarily in its delivery method and accessibility. Broadcast TV uses radio waves transmitted from towers to reach viewers, allowing anyone with an antenna to access it for free. In contrast, cable and satellite services require subscriptions and equipment like cable boxes or satellite dishes. This distinction highlights how broadcast television remains a more universally accessible option for audiences.
• What impact did the transition from analog to digital broadcasting have on the broadcast television industry?
  • The transition from analog to digital broadcasting had a significant impact on the industry by improving picture and sound quality for viewers while also increasing the number of channels available on the same frequency. Digital signals are less susceptible to interference, leading to clearer reception. Additionally, this transition allowed broadcasters to offer new services like high-definition programming and multicasting, where multiple channels can be transmitted simultaneously on one frequency.
• Evaluate the role of broadcast television in shaping public opinion compared to streaming services in today's media landscape.
  • Broadcast television plays a crucial role in shaping public opinion due to its broad reach and historical significance as a primary news source. Major news events are often covered live on broadcast networks, influencing immediate public perception. While streaming services provide on-demand content that caters to specific viewer preferences, they typically lack the same immediacy and broad audience engagement that broadcast TV offers during significant national events. This contrast highlights how traditional broadcast media still holds power in informing and influencing public opinion in ways that streaming platforms may not.
