Three other Americans who have extensive experience in television news, but aren't working there currently, will join Al-Jazeera as senior vice presidents.
David Doss, a producer for news shows at ABC and NBC News who had most recently been producing broadcasts for Anderson Cooper at CNN, will be in charge of news programming.
Marcy McGinnis, currently teaching journalism at Stony Brook University, will be responsible for news gathering, similar to a job she held at CBS News a decade ago.
Shannon High-Bassalik has run local news operations, worked at MSNBC and most recently produced CNN's morning news show before it was remodeled. She will be in charge of documentaries and programs.
Al-Jazeera has announced that a handful of familiar names to American viewers Sheila MacVicar, Ali Velshi and Soledad O'Brien will be doing on-air work for the network. The network also has said it will air a regular newsmagazine, "America Tonight," on weeknights.
O'Brian started work at ABC more than 30 years ago as an intern at "20/20." ABC News President Ben Sherwood wrote to his staff on Monday that "I will miss the sound of her voice, urgent and measured, calling in the middle of the night, when news is breaking somewhere around the world."
