Dateline

"Dateline" has been a staple of the newsmagazine genre since premiering in 1992. Given how long it's been on the air, the show has an extensive archive of in-depth news stories and investigative journalism. This syndicated version offers viewers another chance to watch some of the show's previous content, serving up real-life mysteries and in-depth investigations from the show's 20-plus years on the air. Cases involving murders and missing people are frequent topics on the series that has won multiple Emmys in the news and documentary category.

Forensic Files

Eagle-eyed technical experts prove there is no such thing as a perfect crime as they assemble the pieces every criminal leaves behind. Dramatic crime re-creations and, sometimes, part of the investigations are a staple of the series. Some of the re-creations include alternate versions of the crimes, which are disproved by science. The show's episodes follow each case from the initial investigation until it reaches its legal resolution.

30 for 30

As part of its 30th anniversary celebration, ESPN looks back at notable sports happenings that occurred from 1979 to 2009 with this documentary series featuring 30 films from some of Hollywood's finest directors and producers. Peter Berg, Barry Levinson, John Singleton, Spike Jonze, Dan Klores, Barbara Kopple, Ron Shelton and Albert Maysles are among the filmmakers involved, and the stories told include the shocking trade of Wayne Gretzky in 1988, the Baltimore Colts' nighttime move in 1984, Reggie Miller's rivalry with the New York Knicks, the death of Len Bias in 1986, a profile of George Steinbrenner and his family business, and a look at Michael Jordan's attempt at a baseball career. A new series of 30 films premiered in October 2012 with "Broke," about the challenges athletes face in managing their money.

The Americas

Tom Hanks narrates a 10-episode television event from the executive producers of Planet Earth, exploring the extraordinary worlds and wildlife of North and South America.

Each location comes alive in never-before-seen footage showing the unique connectedness of the land that millions of people call home.
