The last night of the Democratic National Convention has been moved to Denver's INVESCO Field at Mile High Stadium, which can accommodate more than 75,000 people. (See related discussion here.)

After months of planning and spending millions to prepare for covering the convention, the national news media says not so fast.

When the news was first announced, early reports said that the networks considered not covering the speech at all, due to the logistics of setting up in two locations.

They have toned that down a little today, saying the last minute change makes coverage "enormously more expensive" but that they are looking at ways to reallocate resources. According to Politico:

"We want to anchor at it," one broadcast executive said. "[But] do you need to be there to anchor for all four nights? That’s something that we are asking ourselves."

"We are still planning to carry the most significant appearances and speeches from Monday on, in primetime," he noted. "It doesn’t seem smart to invest in a full anchor setup at both locations when the candidate is only going to show at one location."

The broadcast executive added that Obama’s decision will, at a minimum, lead the broadcast networks not to go "whole hog at the Pepsi Center," which is nearly two miles from the outdoor stadium.

In announcing the change of venue for Obama's presumed acceptance speech, DNC Chairman Howard Dean said "The Democratic Party is nominating a true change candidate this August, and it is only fitting that we make some big changes in how we put on the Convention. Senator Obama's candidacy has generated an enormous amount of excitement and interest, not only in the Democratic Party but also in the 2008 Convention. By bringing the last night of the Convention out to the people, we will be able to showcase Barack Obama's positive, people-centered vision for our country in a big way."
