 In the spring of 2000, ORF in Austria and RTL2 in Germany decided to buy the broadcasting rights to the shows Big Brother and Expedition Robinson as they wanted to begin airing a new "reality soaps" genre.
 Neither show was quite as big a success as RTL2 had expected, however both were renewed for a second season (Big Brother would eventually be renewed for at least ten more).
 Following the first season, ORF chose to no longer broadcast Expedition Robinson leaving only RTL2 to air a second season.
 For an unknown reason in 2001 RTL2 decided to produce a show that was almost identical to Expedition Robinson known as Gestrandet.
 Gestrandet proved to be a ratings failure and after 2001, Expedition Robinson no longer aired in Austria or Germany.
Expedition Robinson was the Swiss version of the Swedish reality show Expedition Robinson and it debuted in 1999.

 Joker Johnny Leinonen also entered the competition in episode cycle 3 as part of the South team after buying his spot in the contest.
 Along with this twist, from episode 3 on any contestant voted out of either of the original teams would be sent to Team X to compete in a duel with a member of Team X (chosen by the last person to win a duel).
 Another twist that occurred in the same episode cycle was Frida Lundell's re-entrance into the competition following the voluntary exit of Tina Dadasvand.
 As an unexpected twist, Frida Lundell sold her spot in the game in episode cycle 4 in exchange for a sum of money.
 Following the sudden ejection of newer Team X members Gabriella Kopasz and Nicholas Nath due to rule breaking, the recently eliminated Rasmus Nilsson and Maryam "Shante" Shekhanzai returned to the game.
 Following the initial merge of the North and South teams, the Robinson tribe competed against Team X in immunity challenges.
 If Team X won the challenge, then Robinson would be forced to vote out one of their members (or send them to duel someone in Team X), but if Robinson won they would vote to send one of their team members to Team X.
 When a second merge occurred in episode cycle nine, it was revealed to the contestants that recently eliminated contestants Jerry Forsberg, Johanna Hakala, Dan Karlsson, Johnny Leinonen, Mikael Lundell, and Rasmus Nilsson had been moved to a secret location called "Calm Island", where they had been competing for two spots in the final merge tribe.
 Of the six competing for the two spots, only Dan Karlsson and Mikael Lundell were successful in earning spots in the Robinson tribe.
 At the end of the season, both the jury and the public were allowed to vote two of the eliminated contestants back into the game for the final four.
 The public chose Johanna, while the jury voted Jerry back into the game.
 In addition to this the public was allowed to allot ten jury votes among the two final contestants through the results of a public vote.
 Jerry Forsberg eventually won the season with a jury vote of 11-9 over Fike Najafi.
 Jerry received three of the public votes to Fike's seven.

 Ultimately, Christer Falch won the season over Hanne Cecilie Akre by a unanimous jury vote of 8-0.
 As Christer was seen as the mastermind of the dominant alliance this season and was also seen as the best player, he would take over as host of the show from season 2 on.
