Talkback and Thames merged in 2003, the resulting new company was named talkbackTHAMES. The two brands continued to be used separately on all productions until 2005.
In 2005, the two brands ceased to be used independently, thus all productions became made under the talkbackTHAMES name.
In 2012, FremantleMedia split Talkback Thames into four companies, Talkback for comedy, Thames for entertainment, Boundless for factual and Retort for indies.
In 2018, FremantleMedia was acquired and absorbed by DHX Media, causing all four of those labels to become part of the company.
