"Good Morning America" celebrated its 40th anniversary by bringing together hosts, weather anchors, correspondents and other contributors to ABC's morning show over the last 40 years at the Times Square in New York for the "40 for 40" live stream on Wednesday.

"Every one of your favorite faces from 'GMA' is back," host Robin Roberts announced at the start of the show's 40th anniversary special broadcast, according to KOMO News.

Roberts started off by introducing the guests, which included former hosts David Hartman, meteorologist Sam Champion, Charlie Gibson and Diane Sawyer. "You are our foundation," Roberts said, according to The Orlando Sentinel.

The teams shared memories of their time on the news show. Gibson recalled an experience working with Sawyer, who he anchored the show with on her first day.

"What I remember best is at the end of the show, 'cause I had done this before, and you'd done it with CBS but you hadn't done it for years and years, and I remember at the end of the show, you just collapsed on the desk with your head down," said Gibson, according to E!.

"I was a magazine reporter, I was on the plane to Afghanistan all the time, it never occurred to me that being in this studio was going to be a decathlon," Sawyer quipped. "I couldn't find the cameras and I was going to the wrong interviews."

Hartman, who hosted the first-ever GMA show on Nov. 3, 1975, called anchoring the show "a giant privilege." He recalled a trip to the Soviet Union for the show during the Cold War era and coming back home and kissing the driveway of his house.

Gibson also remembered going to work after the 9/11 attacks, revealing that he and Sawyer had tears in their eyes as they held each other's hands for support, watching the footage of the terrorist attacks.

Other hosts who attended the "Good Morning America" 40th anniversary broadcast included Joan Lunder, Josh Elliot, George Stephanopoulos, Lara Spencer and Amy Robach.
