In 2016, Firth and Theasby launched BOSH.TV, a mantra they took into their video production style. The duo adopted a camera style similar to that of other YouTube food brands like
BuzzFeed Tasty, with the hope that the vegan nature of their content would help set them apart. BOSH's initial success came in the form of a 'healthy sushi cake' video, which hit 3.5m views on
Facebook, and a viral 'watermelon Jagerbomb' video which racked up 20 million views across all platforms. A profile in
The Times dubbed them "the vegan
Jamie Olivers". In 2018, BOSH! released their first vegan cookbook
of the same name. It became the UK's best-selling vegan cookbook of all time, and one of the 50 best-selling UK cookbooks. They subsequently published several further cookbooks and the book
How to Live Vegan. Their first book reached 350,000 UK sales in 2018. By 2022, the pair had reached a million sales from books published in 60 countries in eight languages. At this point the revenue from UK print sales (excluding
lockdown periods) was £6million, from 600,000 sales. Alongside their range of cookbooks, Firth and Theasby brought BOSH! to British television screens in 2020 with their
ITV1 show
Living on the Veg. was ITV's first vegan cooking programme, and featured a series of recipes cooked by Firth and Theasby and a guest who talks about food and their work.
