The show moved from the ABC News headquarters in Manhattan 's Lincoln Square district to its present home at the Times Square Studios on September 13 , 1999 . The new location made it possible for the program to feature a live audience inside the studio , similar to the " Window on the World " set used by '' Today '' . Under Ross , '' Good Morning America '' became a competitive 24/7 news operation with more exclusive bookings , news and live stock market updates for West Coast viewers and new on-screen graphics that included a news ticker . '' Good Morning America '' began originating entire shows from unique locations , which , according to Nielsen Media Research , resulted in more people watching the program and for longer periods of time . '' GMA '' became the first to originate a live show from an aircraft carrier during wartime ( the U.S.S. Enterprise ) , from The White House ( after the Columbine shootings ) , from The Pentagon ( for the reopening of the wing damaged during the September 11 attacks in 2001 ) , from The Vatican ( for the 25th anniversary of John Paul II 's election as Pope ) , and from the Tower of London ( on the 50th anniversary of Queen Elizabethʼs accession to the throne ) . Viewership during this time increased by nearly 1 million households , and revenue soared
