I find it remarkable how good ideas can be purchased to be made lot bigger than originally assumed. Let's take for example feature film "The Ring" (2002).
"The Ring" (2002) is American psychological horror film that have grossed almost quarter of the billion dollars worldwide. The idea for the film was originally adapted from Japanese novel "Ringu" written by novelist Koji Suzuki in 1991. Japanese made the best they could adapting the novel but due to low budget and perhaps lack of professional skills of film-making, in my opinion, turned out to be not attractive to audience as American version. Americans loved the idea so they purchased it and made something bigger and enthused audiences. The film made massive success in US and most importantly worldwide. If it wasn't for the bigger budget and mastermind director Gore Verbinski (Pirates of the Caribbean) the film wouldn't had made that big.
The same way TV shows work like "Who Wants to Be a Millionaire" or "Weakest Link" which are or had been ran in numerous countries. I do like the idea of purchasing rights for something that has already been made and redo into something better.
