It is really surprising how media magnifies things, especially when an iconic TV figure is behind those actions. Oprah Winfrey's Big Give gained enormous popularity around America and here in the Middle East due to broadcasting the show on MBC 4. The idea is about giving money, which has to be a person's own money, to those who are in need in order to be paid back an even more amount of money!
Ironically this idea, which is thought to be new to the American public, is previously known here in our Islamic societies! It is also mentioned in our holy book, the Holy Qura'an! So the idea is not original and not so brand-new! It is what we refer to as "Zakat" -charity- in Islam.
