If your going to try to sell video to a news agency/station, you better have a 333 and follow it completely, including being a licensed pilot.
Your not going to get great footage, then arrange a deal to sell it (unless you happen on something that the timing was perfect), chances are someone would have a relationship in place to sell any video they may come up with. If your doing that, I don't see a regular tv stations doing something without you being completely legal. Now an internet based operation, sure they have nothing to lose, but the majority of the tv stations today are owned by very, very large corporations with lots and lots of lawyers, who want to make sure everything is 'proper'
