It was formed in 2006 by the merger of market leader Grundy Television and comedy specialists Crackerjack Productions, which had both been acquired previously by Fremantle.

Realising that in order for Grundy's to thrive, the company diversified from solely producing game shows to making serial drama, telemovies and children's fiction.

Grundy's first success in the serial drama genre came during the 1970s with The Young Doctors (1976), The Restless Years (1977) and Prisoner, which grew into a worldwide cult hit from its launch in 1979.

When it was sold to US broadcaster, KTLA, in August 1979, it was such a success, that Prisoner: Cell Block H (as it was known in the US and UK) was syndicated to over 30 local TV stations, and remained popular until around 1982.

The BBC dropped Neighbours after refusing to sign a new ten year contract with Fremantle, valued at over 300 million GBP - three times the fee they paid previously.

Neighbours was the highest-rated daytime show for the broadcaster for several years, however, changing viewer habits and demographics saw Channel 5 renegotiate their contract with Fremantle.

The full effect of this strategy was unrealised however, when Channel 5 dropped down to showing only two weekly episodes during the COVID-19 pandemic, therefore, putting the UK behind Australia once again and this situation was never resolved - UK broadcasts then overtook Australia when 10 Peach reduced their output to four weekly episodes, whilst Channel 5 carried on airing five.

Based in St Leonards, Sydney, it concentrated on comedy-related projects, with forays into light entertainment, music, factual and reality television.

In 2018, Fremantle reached an agreement with Israeli company Keshet International for rights to produce adaptations of its non-scripted formats in Australia and New Zealand.
