This summer Discovery is launching a "green" television channel, called Planet Green. ABC newsman Bob Woodruff is slated to anchor an eco-friendly newscast for the new network. The newscast is described as "in-depth news for half an hour each week."

It'll be interesting to see what the story count is for this half hour of news. CBS Sunday Morning is something that I would consider to look "in-depth" at stories and it takes an hour-and-a-half to do that each week. The "green" newscast will focus on scientific analysis, as well as debates on issues. It's being produced by ABC News, where Woodruff is a correspondent.

This is a very different direction for Woodruff, who was briefly co-anchor of ABC World News Tonight until he was seriously injured in a roadside bombing in Iraq.
