Moreover, Wikipedia is a nonprofit, free-ofadvertising
social entrepreneurship venture that is exclusively
financed by donations. Wikipedia runs regular calls
for donations using slogans such as: 81 “Please help us
feed the servers,” “We make the Internet not suck. Help
us out,” and “We are free, our bandwidth isn’t!” Calls for
donations also come in the form of personal appeals by
co-founder Jimmy Wales. The question arises whether
the donation model is sustainable given not only the
increasing demand for Wikipedia’s services, but also the
emergence of competitors.
