The next series of reality television show Big Brother in Germany will last an entire year.
The UK version set up a rich and poor divide in 2002
The fifth series of the show in Germany begins on 1 March - with nine contestants competing for a prize of 1m euros (£700,000).
An Endemol spokeswoman said the house will be divided into three sections - "rich", "poor" and "normal" - for the duration of the series.
The German series is filmed in a house outside Cologne.
Programme-makers are looking for a cross-section of people to take part in the show, including millionaires, academics and factory workers.
The German Big Brother has continued to be a huge success but frisky contestants have proved a problem for producers.
Two contestants were even slapped with a two-day no touching ban to keep them away from each other because the coverage was deemed too steamy.
Once the ban was over the couple headed straight for a bed.
And two contestants from the second series were married after leaving, but there was talk of a divorce soon after.
Series four produced another romance when two contestants announced their engagement live on air.
