Why are LED screens used in news studios instead of built-in sets?

• A. So they can switch out the background from show to show, giving each program its own look
• B. It reduces production costs by eliminating physical sets
• C. It improves camera reliability during broadcasts
• D. It enhances audience interaction through live polls

Answer: (A)

LED screens provide flexible, quickly changeable backdrops for each program. Their large digital canvases can display high‑resolution imagery, video, or graphics, so the background can be switched to give every show its own look without rebuilding the set. This allows branding and mood to match the program in seconds, boosting visual impact and production efficiency. While some cost considerations exist, the standout benefit is the ability to vary the background from show to show. The other options miss the main point: camera reliability isn’t driven by the backdrop, and audience polls are about content, not the set design.
