# Inside the Factory

Inside the Factory is a British television series produced by Voltage TV for the BBC. The first episode was broadcast on BBC Two on 5 May 2015. Each episode explores how a specific product is made inside a factory. The 2024 series is presented by Paddy McGuinness, Cherry Healey and historian Ruth Goodman who provides a look at how products came to exist as we know them today.
Initially both Gregg Wallace and Healey visited the factories together, but since the Christmas special of 2017, each of the three presenters are in separate locations, forming different segments of the programme.
Wallace, who presented the programme from its first episode, announced in 2023 that he was leaving the programme, with his last episode airing as the eighth series finale in 2024.
On 22 August 2023, it was announced that Paddy McGuinness would be the new presenter, replacing Wallace for the ninth series in 2024.
