how many big brother seasons

There have been over 500 seasons of Big Brother worldwide across all countries and regions in the franchise.

Quick Scoop: Core Answer

  • As of early August 2023, there were 508 total Big Brother seasons across more than 63 countries and regions.
  • Since the franchise is ongoing (with new series like Big Brother UK and Big Brother US still airing in 2025), the real-time total in 2025 will now be slightly higher than 508 , but 508 is the last clearly documented global count.

UK Big Brother Seasons

When people ask “how many Big Brother seasons,” they often mean the UK version, because that is the original English-language series.

  • The civilian UK Big Brother has reached 22 main series by 2025 (Channel 4 + Channel 5 + ITV revival).
  • The 22nd series ran in 2025 on ITV and was noted as the longest ITV season to date, ending in mid‑November 2025.

US Big Brother Seasons

The American version on CBS is also a very common reference point.

  • The US Big Brother reached its 27th season in 2025, which was promoted as the 25‑year anniversary season.
  • In addition to those 27 regular seasons, there are also spin‑offs like Celebrity Big Brother (three seasons so far) and Big Brother: Reindeer Games , but these are usually counted separately from the main season tally.

Global Franchise View

Looking at the franchise as a whole gives the most impressive number.

  • The Big Brother format has been adapted in over 63 countries and regions , covering Europe, the Americas, Asia, Africa, and Oceania.
  • Across all of those adaptations, the last published global count lists 508 seasons of Big Brother as of 5 August 2023, including regular and celebrity versions.
