Both of these reality shows are based on inventions.
In Dragon's Den regular folks must pitch their inventions in front of a bunch of super-rich, successful entrepreneurs, who will inject money into the business in exchange for a variable controlling interest. But usually they say "no" to ridiculous ideas (like diapers for pets). Great show!
There's a UK version:FOREVER CHELSEY by Omayma Moharram
Omayma Moharram has developed a specialty line of diapers for dogs and cats.
and a Canadian version:
Inside the Dragons' Den
Here's another interesting one from the UK, also involving inventions. It's just started here in Canada:
The Reinventors
Dick Strawbridge and his son are on a mission to bring back to life great inventions of the past, and discover what they reveal about the way people lived then.
From the spinning jenny to the turnip cutter, The Re-Inventors unearths some of the weird and wonderful contraptions of the past, not only bringing the invention back to life but revealing through the invention’s story, the local history of the area.
Using their ingenuity and skill Dick and his team must solve a design problem from the past in the space of just 24 hours. In re-designing, re-engineering and re-testing these fantastic machines, the Re-Inventors will reveal the lost history of the invention, shedding light on both the device itself, its inventor and society at the time.
