Bill Chappell

Bill Chappell is a blogger and producer who currently works on The Two Way, NPR's flagship blog. In the past, he has coordinated digital features for Morning Edition and Fresh Air, and edited the rundown of All Things Considered. He frequently contributes to other NPR blogs, such as All Tech Considered and The Salt.

Chappell's work at NPR has ranged from being the site's first full-time homepage editor to being the lead writer and editor on the London 2012 Olympics blog, The Torch. His assignments have included being the lead web producer for NPR's trip to Asia's Grand Trunk Road, as well as establishing the Peabody Award-winning StoryCorps on NPR.org.

In 2009, Chappell was a key editorial member of the small team that redesigned NPR's web site. One year later, the site won its first Peabody Award, along with the National Press Foundation's Excellence in Online Journalism award.

At NPR, Chappell has trained both digital and radio staff to use digital tools to tell compelling stories, in addition to "evangelizing" — promoting more collaboration between legacy and digital departments.

Prior to joining NPR in late 2003, Chappell worked on the Assignment Desk at CNN International, handling coverage in areas from the Middle East, Asia, Africa, Europe, and Latin America, and coordinating CNN's pool coverage out of Qatar during the Iraq war.

Chappell's work for CNN also included producing Web stories and editing digital video for SI.com, and editing and producing stories for CNN.com's features division.

Before joining CNN, Chappell wrote about movies, restaurants and music for alternative weeklies, in addition to his first job: editing the police blotter.

A holder of bachelor's degrees in English and History from the University of Georgia, he attended graduate school for English Literature at the University of South Carolina.

Islam is growing more rapidly than any other religion in the world, according to a new report by the Pew Research Center that says the religion will nearly equal Christianity by 2050 before eclipsing it around 2070, if current trends continue.

"The main reason Muslims are growing not only in number but in share worldwide is because of where they live," Alan Cooperman, Pew's director of religion research, tells NPR's Tom Gjelten. "Muslim populations are concentrated in some of the fastest-growing parts of the world."
