Here is TLC's preview write up:
9:00 pm Little People, Big World: Wedding Farm
A New Chapter
To start their wedding business, the Roloffs find themselves racing the clock to completely refurbish several buildings and landscape a huge area for ceremonies in time for the summer wedding season.
There also is an article from the Oregonian with quotes from Matt, Amy and the General Manager of TLC, Amy Winter.
One thing that comes out of the article is that the GM of TLC states that it was Matt who approached TLC about doing a series about a 'Wedding Farm'.
Both parties also make it sound as though they want to keep the Roloffs on television for many more years to come. Although keep in mind, Matt Roloff did once give an interview to a local Portland TV station in July stating that the series Little People, Big World would continue for at least 2 more years and a month later TLC announced they were pulling the plug on the weekly series.
Some long time followers of the Roloffs might recall that Amy used to insist (a long time ago now) that their lives did not revolve around being on television and now being "reality TV stars" has basically become their career.
Amy Winter does note that it depends on the ratings for these "Wedding Farm" episodes, but the article goes on to talk about how in addition to the "Wedding Farm" episodes, they plan on continuing the "Update specials (which many viewers have taken issue with the word "update" since so many *real* happenings in the lives of the Roloffs are never mentioned on TLC). They also float out the idea about an episode about the Roloffs growing Christmas trees
Matt is still insisting that the "Wedding Farm" is a real business and not just a plot gimmick to get back on television, although I think it's fair to say that many are skeptical about that considering no one has been able to find a website or information about their "real" wedding business. There is no information about a Roloff Wedding business on the Roloffs website. In the article Matt states he posts advertisements about the Wedding Venue on Craigslist.
