Broadcast has bandwidth. Computers have brains. Why are these two competing? Broadcasting a signal that means something to computers, and having computers then marshal that for users is way more profitable.

Easy place to start - start hiring a small TV station for an hour in the morning, somewhere in amongst the informercials, and broadcast a signal that people with TV Tuners can decode. Using some variation of colour 3D barcodes, say. Have the TV Tuner decode software use this hour to pump content into squid or some other form of web cache.

Monetisation strategy: give people the ability to vote on what gets broadcast based on their cache logs.
