That only existed for television news and only because the FCC required television stations to air after-work news without commercials (making it a cost center) as a condition of their FCC airwaves licenses. Reagan's administration dropped that rule, deregulating television stations, turning news departments in to potential profit centers, and further merging entertainment and journalism.
As far as I can tell, the current administration and Congress are more interested in moving further away from regulations than closer to the pre-Reagan regulation regime.
To be fair, I don't think it will work today even if that regulatory rule was re-implemented. At the time, the vast majority of the US only had a choice of 3 major television networks, which were more or less equally non-partisan. Currently, there are too many channels and people that tune into certain channels do so to avoid being challenged by ideas they don't already believe.
