The success of Daredevil can have some impact, but Disney owns ABC and Warner Bros owns The CW. They are pocketing money at every step of the process, something which isn't the case for the Netflix shows where they are losing certain revenue streams. FOX won a bidding war for Gotham, so there were probably other interest parties. As for stuff like AMC, DC has sold them Preacher. We're still waiting on it. They have given TNT Titans, we're still waiting on that too. It is also a question if licensing their stuff to such tiny channels isn't beneath them? Starz gets way less viewers than The CW.
In the case of Marvel's Netflix deal, it was a very specific package they put together and shopped it around: http://deadline.com/2013/10/marvel-...-series-a-mini-for-vod-cable-networks-611826/
They weren't offering one show, they were offering 5 shows totaling at least 60 episodes, to be signed right off the bat. There was a bidding war and Netflix won.
