Are the three national broadcast news networks preserves for male supremacy? Judging by which correspondents got the most air time in 2010, it would seem so, according to figures compiled by the Tyndall Report.

Politico's Mike Allen points to Tyndall's top 20 compilation and notes the ranking:

"ABC's Jake Tapper ... ABC's David Muir ... ABC's Jonathan Karl ... CBS' Chip Reid ... NBC's Anne Thompson ... CBS' Mark Strassmann ... NBC's Tom Costello ... CBS' Nancy Cordes ... NBC's Chuck Todd ... ABC's Sharyn Alfonsi ... NBC's Pete Williams ... CBS' Anthony Mason ... CBS' Ben Tracy ... NBC's Andrea Mitchell ... ABC's Brian Ross ... ABC's Dr. Richard Besser ... ABC's Dan Harris ... CBS' David Martin ... NBC's Kelly O'Donnell ... NBC's Robert Bazell."

Fifteen of the top 20, or 75 percent, are men. Now, shouldn't network news readers and reporters "look like America," as the multi-cultural diversity mongers on the Left are constantly harping?

Other interesting tidbits on Tyndall: Bet you thought Obamacare was the biggest story of 2010, or maybe the 2010 mid-term congressional election. Wrong on both counts.

The biggest story, according to Tyndall's compilation of the air time devoted to the top 20 stories, the Deepwater Horizon disaster was tops, followed by the Haiti earthquake, and continued fighting in Afghanistan. Health care reform was only the fourth most covered story, with winter weather in fifth.

The mid-term election? Election overviews were seventh, while the GOP's biggest mid-term win since 1938 rated only 11th. Others in the top 10 included unemployment, Toyota's sudden acceleration crisis, anti-terrorist security measures and the Chilean copper miners.

Go here for more from Tyndall in its yearend review. While you're there, check out the breakdowns by issue where you will find Don't Ask Don't Tell and the McCrystal resignation were the two biggest defense stories of the year, followed by military casualties cope with post-combat disabilities, hardships on military families and Iran's nuclear program.

There is a there because notably absent from the next five is coverage of the gallantry, courage and humanitarian work of the U.S. military. Apparently, the three network news operations couldn't be bothered.
