That’s the main argument of MSM defenders—that without them there will be no original, informational news-gathering and investigative reporting and that the blogs and talk radio just hash out the stories and issues of the day after the fact.
We can all think of the notable exceptions; Michael Yon in Iraq for instance. Many of the more notable bloggers and talk radio mavens do occasional shoe-leather reporting and researching, conduct interviews and attend events, etc. but how much does that really add up to?
If you don’t read/watch the MSM, you are uninformed.
If you DO read/watch the MSM, you are MISinformed.
