Her challenge is to revive the flagging channel, which has cut staff and expenses as the economic downturn has eaten into advertising and ratings have fallen.

CEO and Co-Chairman of DreamWorks Studios
U.S.
With colleague Steven Spielberg, in July reportedly inked an $825 million deal with India's Reliance, a Bollywood stalwart run by the billionaire Ambani family.

Perhaps as a result, I see girls worldwide growing up with a new sense of themselves that I and most women of my generation were not given. These girls are powerful," she stated in March.

Africa's first democratically elected female head is facing a political bombshell. After testifying before Liberia's truth and reconciliation commission in February that she gave up to $10,000 to a rebel group headed by former President Charles Taylor (now under arrest at the Hague), she was hit by a recommendation that she and other senior politicians be barred from office for 30 years for allegedly aiding Taylor's overthrow of President Samuel Doe in 1989. Johnson-Sirleaf has said she won't resign.

Instead, Halonen is focused on cleaning up the Baltic Sea and promoting bilateral trade ties.

Mary McAleese
President

In September, Ireland became the first Eurozone country to fall into an official recession, and the country's unemployment rate surged to 11% in March, the highest level for nearly 13 years. McAleese remains committed to the peace process in Northern Ireland, and credits it to the role women have played in that process. "It is absolutely no accident that the peace and reconciliation, and indeed the economic progress, that eluded us generation after generation for hundreds of years, has at last come to pass in an Ireland where the talents of women are now flooding every aspect of life as never before," she said.
