Are paywalls going to be new normal in media?

More and more we are seeing example similar to Andrew Sullivan's example as noted in this TechCrunch article:

After mostly giving away their on-line content for free from the get go, most publishers are now second guessing that decision and beginning to charge for access to their news. It makes sense, and I never understood why they gave it away for free in the first place. I know that for me personally, I have no problem paying for great, original content and assumed that if I paid for the print version, why wouldn’t I pay for the online version too?

What remains to be seen, however, is can some of the media put the genie back in the bottle? I think it will become more challenging to start to charge someone after they have been getting it for free for a while. The New York Times was successful in doing that but then again, there aren’t too many New York Times out there.

No doubt change is coming in the way we view and pay for news content on line.
