That was interesting. Highlights for me:

The Chorleywood bread process allows the use of lower-protein wheats and reduces processing time,[5] the system being able to produce a loaf of bread from flour to sliced and packaged form in about three and a half hours. This is achieved through the addition of vitamin C, fat, yeast, and intense mechanical working by high-speed mixers, not feasible in a small-scale kitchen.

The process significantly reduced fermentation time and allowed greater use of non-imported wheat, which helped reduce the price of bread.[4] According to a representative of the British Federation of Bakers, "UK bread is around the cheapest in the world."[5]

As of 2011, 80% of bread made in the United Kingdom used the process, which has also spread to other countries such as Australia, South Africa, South America, Turkey and France.
