10 Glass Ceilings Not Yet Cracked

A dozen Fortune 500 companies may have female CEOs, but many glass ceilings remain to be cracked by US women. The BBC spots 10:

• White House Chief of Staff. "CJ Cregg of TV's The West Wing might make the list for best chief of staff of all time, save for the fact that she's fictional."

• Navy Seal. Women aren't allowed to serve in ground combat units, but earlier this year the head of military's special ops division trumpeted the notion of a woman Navy Seal.

• Head writer for The Simpsons. After 20 years, the show still has no female show-runner. In fact only 10% of its scripts are written by women.

• Baseball GM or NFL Commissioner. Woman have owned teams, but are yet to head a league or general manage a baseball team.

• Chess World Champ. Grandmasters, yes, but no world champion as of yet. "I'm seeing more girls playing chess than 10 years ago, but it's still not even close to half," says one chess writer.

• US President. "The United States is one of the last Western countries to have never had a female head of state."
