Blogging is not a type of journalism, but many journalist blog.  Blogs tend to be less formal, more 1st person accounts and can pretty much be done by anyone.  To confuse Blogging with Reporting is to confuse the professionals with the amateurs.  As for citeable instances of "news reporting for a network", yes, the Fox News Network, see the link at Foxnews.com.

Please note the difference between blogging and reporting is substantial and the current title is mislead.   Matt Sanchez
