The Power 50

Business has its ups and downs, and so, naturally, do women in business. (Bye-bye, Martha!) But the story of this list is one of achievement: The credentials of these women, including the 13 newcomers, are the strongest yet.

2006 rank:  41
Age: 49

Since Pascal's promotion last year, Sony has had more than a dozen hits, including The Da Vinci Code, Casino Royale, and The Pursuit of Happyness. Revenue grew nearly 30%, to $8.2 billion, in 2006, and included a record $3.3 billion in theatrical receipts - all without the help of Spider-Man. Pascal drives creative success at Sony Pictures, while co-chair Michael Lynton takes care of the numbers.
