Citizen science has existed for as long as science. At one point, being an amateur was actually more prestigious than doing science as an occupation, in the same way the amateur detective Sherlock Holmes was considered superior to the police, because he did it as passion rather than blue collar occupation.Though bird watchers and amateur archaeologists still exist, and amateur astronomers are likely on par with paid government scientists when it comes to new discoveries, citizen science has become more widespread than ever, and that is all thanks to "gamification" of science; making scientifically tedious work fun for people who are passionate, but who aren't going to turn it into careers.
