NBC wants more episodes of three of its newest reality shows, ordering additional episodes , our friend Joe Adalian reports for TheWrap.

The three shows are  "The Marriage Ref," "Who Do You Think You Are?" and "Minute to Win It," The Wrap reports.

The Jerry Seinfeld-produced "Ref" has gotten an additional 13-episode order, with three of those episodes earmarked to air this season.

"Minute" has an additional 10 episodes coming its way, airing throughout this season and through the summer. "Who Do You Think You Are" also received an order for eight more episodes.

While not a blockbuster in the ratings, all three shows have performed solidly based on their time periods.
