Diane Sawyer Looks Back On "GMA" Memories (VIDEO)

Diane Sawyer looked back Friday morning at 11 years of "GMA" memories as she gets set to trade in the 4AM wake-up-calls for the "World News" anchor chair.

Sawyer recalled her first day anchoring the program with Charlie Gibson in 1999 and the almost 3,000 shows since then, shows that brought her around the globe and in the center of all of the decade's most newsworthy stories. Sawyer recalled covering 9/11 from Ground Zero and Hurricane Katrina from New Orleans, Randy Pausch's "Last Lecture," and her interview with Nancy Reagan, in which she described her husband's last moments.

"Every day here has been a grateful journey forward with the 'GMA' family around me," Sawyer said in the package, remembering when Charlie Gibson became a grandfather, when Joel Siegel died, when Chris Cuomo's children were born, and when Robin Roberts was diagnosed with cancer.
