"Natural disasters dominated the year," Tyndall writes. "With Hurricane Katrina in the lead, they attracted triple their average annual attention." NBC "made Katrina its signature story."

CBS stuck to the Iraq beat "most tenaciously," but "no Baghdad-based reporter made the Top 20 ranking" of most heavily-used reporters.

Also, "ABC invented the Culture Wars as a new news beat, with a fourtopic combo: church-v-state, the culture of life, coarsening mass media, and sexual morality issues. Reporter Dan Harris led the coverage along with DC-based Jake Tapper (155 min)."
