Pubradio correspondents win Polk Award

Two pubcasters are sharing a Polk Award. Alex Blumberg of "This American Life," produced by Chicago Public Radio and distributed by PRI, and Adam Davidson of NPR, won for their collaborative report, "The Giant Pool of Money," explaining the events leading up to the subprime mortgage crisis. The prestigious Polk Awards, bestowed by Long Island University, are named for George Polk, a journalist who died in May 1948 covering the Greek civil war.
