Most stations in the US are now posting content transcribed directly to their own websites with clips of the appropriate story already. Promotion is the then directed to twitter/fb on an automatic or selective basis. Is this basically what you are talking about? In the scenario above, people find out about the content through search or directed discovery or one of the aforementioned social streams.

If so, then please understand that I don't think you've thought through your hypothesis and gauged demand enough. News shows purposefully put the best content at the end of a show because they want people to slog through the 15 or so commercials in the 3 breaks before consuming it. Notice this whenever there is a juicy story or big weather prediction.

Enmass show viewership pays more than selectively pulling out the good bits. AftEr the fact, the value of the content would be zero anyway, so it's repurposed for web use.

I would validate your hypothesis with both the consumer and customers. If you can't see it working, pivot. Perhaps a subscribable video playlist based on topics (like good alerts) not channels (like YouTube).

if you use this idea and it generates revenue, I want 2 percent.
