Broadcast News Timing & Pacing Principles

Short-form audio news reports like Bloomberg News Now, NPR News Now, and BBC Minute succeed on relentless precision and tight writing:

  • The 3-Minute Clock: Standard listener retention drops sharply after 3m30s. Target exactly 180 seconds.
  • Delivery Rate: 155 to 165 words per minute allows maximum information density without sacrificing articulation.
  • Lead Story Weight: The lead story gets 45–60 seconds, secondary macro items get 30–40 seconds, and quick market flashes take 15–20 seconds.
  • Acoustic Branding: Sounders (stingers) serve as mental punctuation between heavy macro news and commercial breaks.
