You should read Amy Robach book she released back in September about her battle with breast cancer.
She talk quit a bit and very openly in the book about why she left Weekend TODAY Show and NBC back in 2012. She doesn't hold back much.
She was very unhappy in her last couple years there.
She was going through a lot of stuff at the time (Stress along with anxiety attacks and other personal things and at one point she had a doctor appointment in early spring of 2012 where she found out her heart was damaged) and said how for the last few years she was not feeling the love anymore at NBC like they (the executives high up not her co-workers. she was still very much respected and love when it came TODAY Show staff) really did not want her there anymore. Her career has hit a dead end and she was not really going anywhere. she been doing Saturday TODAY for 4 1/2 Years. She had until 2010 been filling in for Meredith, Brian, Ann and Natalie but suddenly the calls started coming less and less and then eventually they just stop. She was told by doctors she needed to slow down with working. in 2012 her contract was up soon but she was not hearing at all from NBC about renewal and her agent was not getting any calls and that made her worried.
She admit that she wanted to move up to Weekday TODAY when Meredith announced she was leaving. She wanted the Third Hour co-hosting job on the Weekday Show. she thought (And says it was) her!
When Savannah got the Third Hour Job job she then felt it was time for her to leave. And so she joined ABC. She felt like she had to last chance. This was before the whole Ann curry tihng. Had she knew what was about to happen who knows if she would have stayed or not but when Amy left it made room for Tamron.
I should say she has no animosity for Savannah whatsoever. Just thought I should point that out. she doesn't blame her at all. She does still seem to have some bad blood towards NBC 9and probably rightfully so)
But then after awhile at ABC she also started to feel like they were not doing much with her anymore especially after Robin came back to GMA full time. they then kept promising her that they had something planned for her.
Anyway it was very interesting read. I was surprise at how much details she went into, a Great book overall.
But the same has happened to other Weekend Anchors including Jodi Applegate, Campbell brown, Soledad O'Brien and Maria Shriver. The only weekend Co-anchor who ever got promoted to weekday show was Katie Couric.
