Andy Cohen may be known as the guy who hosts the “Real Housewives” reunion specials and other specials for various spinoff shows that have been created by Bravo. Many people are often calling for spinoff shows for their favorite housewives or reality stars because there's always someone on the show they can't stand. For example, on “The Real Housewives of Beverly Hills,” people always called for Lisa Vanderpump to get a spinoff because they couldn't stand Brandi Glanville.

Or perhaps they were calling for an Erika Girardi spinoff show because they were getting tired of the same drama on the show.

And while Andy Cohen and the producers at Bravo have granted several spinoff shows, including Bethenny Frankel's own spinoff show, Kim Zolciak’s show about her family, and more recently Lisa’s show about SUR, it sounds like the spinoffs are limited.

Too much risk involved in creating a new show

As it turns out, spinoff shows are very risky and they could cause the network a lot of money if they aren’t successful. In other words, Bravo producers choose spinoffs very carefully and it seems like they want evidence that the show is going to succeed before moving forward with a decision to actually film the show.

As for Andy, he doesn't see a spinoff happening for some of the housewives because they simply don't have to fan base to support a large viewership.

Kim Zolciak’s spinoff show has done extremely well and they're already filming a new season for “Don’t Be Tardy.” Kim also has deeply grounded roots in “The Real Housewives of Atlanta” and she has a strong viewership, because of the feud with NeNe Leakes and some of the other housewives prior to leaving the show. In other words, the producers felt that she could carry her own show.

There has to be a history with the reality star

Lisa Vanderpump’s show surfaced because people were curious about SUR. Of course, Lisa is indeed the boss of the show and the restaurant, but the show has become much more but the people working at the establishment, including their personal relationships, the drama between them, and their work schedules.

As it turns out there's a lot more going on behind the scenes than fans initially realized. Some people want to see a spinoff show for Erika Girardi, possibly to follow her journey through the pop world as she continues to climb the charts with her music. But Andy doesn't see it happening.

One could argue that every housewife that has ever been in a franchise has an interesting story to tell that hasn't been featured on the “Real Housewives” show that they were on. But that doesn't necessarily mean that a spinoff show about their life would be a good idea. Of course, some spinoff shows have done really well, including Bethenny Frankel's show about her business and her marriage.

At the time, the show may not have been too interesting for people who are fans of Jill Zarin, but Bethenny was open and honest about the troubles in her marriage.

Shortly after ending the show, she filed for divorce from her husband. Since they are now feuding in the public, their story continues on "The Real Housewives of New York."

Are you surprised that Andy Cohen doesn't see a reality show for Erika Girardi? Do you think she should continue to return to “The Real Housewives of Beverly Hills?”
