Jason Kilar, the CEO of online-video site Hulu, has rediscovered a truism: less is more. Hulu, which is mostly owned by NBC and News Corp., runs fewer ads on the TV clips it licenses from its TV-network parents than they air when they broadcast the same shows. And yet the ads are more effective. This could simply be a novelty effect; everything about Hulu is new, so the ads also draw more notice. But Hulu may be onto something. Why don't networks try running fewer ads on air, too? (Photo via Alarm:Clock)
