Meredith Vieira is the highest-ranking woman in television news on Forbes' 2007 "The World's 100 Most Powerful Women".

The magazine bequeaths the very top spot on the list to German Chancellor Angela Merkel. Vieira comes in at #55, with Diane Sawyer #62, Katie Couric #63, and Christiane Amanpour #74. Anne Sweeney, President of the Disney-ABC Television Group, is #77.

In an interview on Forbes.com, Forbes Senior Editor Elizabeth MacDonald says the women on the list were chosen on the basis of "their title, their sphere of influence, their career accomplishments, (and) the amount of money they have sway over", as well as "what changes they've brought, and what influence they have around the world."
