Showtime, HBO and CNN Garner Peabody Awards April 4, 2012, 12:27 pm The Showtime counterterrorism drama "Homeland," the Comedy Central satire "The Colbert Report" and the cable news channels CNN and Al Jazeera English were among the recipients of George Foster Peabody Awards on Wednesday. The awards, presented by the University of Georgia's Grady College of journalism and mass communication, are considered to be the most prestigious of their kind in electronic media. HBO picked up three: one each for "Game of Thrones," "Treme" and a documentary it showed about Rwanda, "Earth Made of Glass." Its rival Showtime picked up two, one for "Homeland" and another for a documentary it ran about survivors of 9/11 called "Rebirth." CNN also won three awards, for its worldwide coverage of the Arab Spring, commentary by the weekend host Fareed Zakaria, and its annual awards telecast, "CNN Heroes." Other programs honored included "Portlandia" on IFC and "Parks and Recreation" on NBC. "Austin City Limits," the live music television program on PBS, was bestowed with an institutional Peabody award. And the "CBS Evening News" was honored for reporting by Clarissa Ward, a young correspondent who sneaked inside Syria late last year with only a camcorder. The list of other award recipients this year reflects the sometimes eclectic diversity of sources of electronic media in the Internet age. Right alongside BBC.com and NPR was the growing international news site GlobalPost and the Web site for the TED conference, TED.com. And there was the quiz show "Jeopardy!": "Encouraging, celebrating and rewarding knowledge is this Peabody Award winner's legacy," the group's citation read, phrased in the form of an answer.
