One of the most​ impressive, innovative advances in online fundraising over the past decade is the rise of​ crowd-funding websites. While features differ from site to​ site, crowd-funding sites are websites that allow you to set up an online fundraising campaign based around a fundraising​ page, and accept money directly from that page using the​ website's own credit card processor. A certain​ crowd-funding website reported that 131 of 357 technology​ crowd-funding projects were successfully launched in the past year and 345 of 872 film and video​ crowd-funding projects were successfully launched in the past year.
