NBC released a video for 2026 being the network's 100th anniversary. Actual mention of the radio side, though largely TV focused.
No mention of NBC's children's/animation side, outside of DreamWorks/Illumination films. Self-promotion aside, rights would be a concern (they don't own the Smurfs or Alvin and the Chipmunks)... though they do own Woody Woodpecker (who aired on NBC) and some rights to Bullwinkle?
