Does anyone know how the revealing of Nora Roberts as JD Robb affected her career?

I am doing an english paper on Nora Roberts and how her pseudonym affected her career. Does anyone have any sources I could use to find this information?|||She did an interview a couple of months ago where she talked a little bit about her pseudonym. You can find the whole thing on youtube, but here's part one: http://www.youtube.com/user/ThePublisher鈥?/a>|||It did nothing but help her and now she is essentially two best selling authors in one. She was already extremely successful but wanted to try and branch out into another sub-genre (hence using the pseudonym. This allowed her to see the response of the public to the books before putting her romance career at risk while also seeing if the series could be a hit on its own. When she finally reveiled that she was indeed JD Robb, (I believe she did it with the release of Betrayal in Death), there wasn't even really any backlash at all.
