Team Robin Reporting For Duty

The countdown is finally over for Good Morning America's Anchor Robin Roberts. After 174 days of waiting, Roberts returned on Wednesday to the highly-rated morning program. This was Robert's first on-air appearance since she went on medical leave for a painful bone marrow transplant back in August. She inspired many of Good Morning America's viewers to be a part of her journey. Viewers from all over the country took part in "Be a Match" and supported her every step of the way.

Once she reached the 100th day mark of her recovery process, her team of doctors told her the good news, she can go back to work. Roberts took the weeks in early January to get her strength back as well as getting used to those early morning wake up calls. Meanwhile, at GMA, co-workers took their part in getting flu shots and sterilizing the set. And finally after several "dry runs", Roberts was back excited to say those words we have all been waiting for her to say, "Good Morning America".

The two-hour cast featured viewers outside holding welcome back signs and Roberts pictures all over Times Square. Of course news was their first priority to get too. After the first hour, Roberts was greeted by her doctors, nurses, family, friends and even music. Christian singer Mandisa was there to sing her hit "Stronger" which helped Roberts get through her painful journey.

Wednesday's welcome back sure will play a huge factor in ratings with the competition always fierce between NBC'S Today's show. With February sweeps in full effect, things will be getting very interesting in the coming weeks.

Of course Roberts health is still the main focus. While she does have an interview later this week with the Obama's and will be at this Sunday's Oscars, her team of doctors said after today's first day they will keep monitoring her until they know she is ready to go full speed.

You can watch a special 20/20 this Friday on ABC for an exclusive interview about her journey.
