Debate truth checking idea in real time

I read that each debate will be broadcast live on C-SPAN, ABC, CBS, FOX and NBC, as well as all cable news channels including CNN, Fox News and MSNBC among others.

Now if one of those networks promised to put a news ticker banner on the bottom of the screen calling out each lie in real time as it happened that would be a reason for me to watch the debate on that network rather than another.
