The watershed for me was David Brinkley's pronouncement in the '92 election. For the weeks running up to the election, Ross Perot had been proclaiming that the Bush Administration was hiding the fact that the economy was on the brink of total collapse, and that after the election, they would admit it. The networks reported this information without commentary. After the polls had closed across the country, David Brinkley said, "Well, one thing the new President will have going for him is a rebounding economy. We've just received the 3rd quarter reports, and ...". Of course, they'd had these reports for over a week, but all the major media outlets sat on them until after the election.
