Emily Bell's high position among the 2007 Agenda Setters is a measure of the Guardian Unlimited editor's success in managing the evolution of The Guardian's web presence.
She has put the focus on blogging and video content, overseeing a comprehensive overhaul of the homepage and recently launching a US edition of the site.
As one Agenda Setter put it: "The Guardian has been the most effective in not just putting a newspaper online but really changing the whole context - also putting in podcasts, videocasts - and actually also on a wider scale, really very effectively building the world's first global newspaper."
As a journalist, Bell has written widely on media issues and has even interviewed fellow Agenda Setter Rupert Murdoch, who ranks below her in this year's Top 50.
The rise of a younger, more natively web-focused generation of media figures is also underlined by the relatively high placing of Murdoch's son James on the list for the second year running.
Bell, an Oxford University graduate, has been at the helm of The Guardian's network of online brands since 2000, when she was promoted from her post as editor of MediaGuardian.co.uk.
She lists media business, convergence, the new media industry, advertising and broadcasting as specialist areas.

"Blogging's definitely got to the point where there're enough mainstream consumers watching it for the top bloggers to be regarded as agenda setters."
