Facebook has used crowdsourcing since 2008 to create different language versions of its site. The company claims this method offers the advantage of providing site versions that are more compatible with local cultures.
FamilySearch Indexing is a volunteer project which aims to create searchable digital indexes for scanned images of historical documents. The documents are drawn primarily from a collection of 2.4 million microfilms made of historical documents from 110 countries and principalities. Previously, volunteers installed free software on their home computers, downloaded images from the site, typed the data they read from the image into the software, and submitted their work back to the site. A web-based indexing application was launched in 2014, and the installed version was later retired. The data is eventually made publicly and freely available at familysearch.org (the world's largest nonprofit genealogical organization) for use in genealogical research. Over one billion historical records have been transcribed to date.
Folding@Home is a distributed computing project for disease research that simulates protein folding, computational drug design, and other types of molecular dynamics. The project uses the idle processing resources of thousands of personal computers owned by volunteers who have installed the software on their systems. Its primary purpose is to determine the mechanisms of protein folding. This is of academic interest with implications for medical research into Alzheimer's disease, Huntington's disease, and many forms of cancer, among other diseases.
Foldit invites the general public to play protein folding games to discover folding strategies.  Citing Foldit, MSNBC's Alan Boyle reported that "video-game players have solved a molecular puzzle that stumped scientists for years," indicating that they "figure(d) out the detailed molecular structure of a protein-cutting enzyme from an AIDS-like virus found in rhesus monkeys."
Freelancer.com started out in Sweden in 2004 as GetAFreelancer.com, and is now owned by Sydney, Australia-based Ignition Networks. M Barrie, the CEO, claims the company is the largest outsourcing site in the world, receiving more global traffic than competitor elance.

Galaxy Zoo is a citizen science project that lets members of the public classify a million galaxies from the Sloan Digital Sky Survey. The project has led to numerous scientific papers and citizen scientist-led discoveries such as Hanny's Voorwerp.
Gaspy is a petrol price monitoring app of New Zealand.
"The Gateway to Astronaut Photography of Earth – Image Detective" is an interactive citizen science hunt for the Earth location of images taken from space by astronauts since the 1960s. Reviewing 1.8 million photos, individuals submit what they believe to be the location of a given photo, and thus accumulate "points" and "badges" on part of the NASA website.
General Electric organized a "Multi-Million Dollar Challenge" to find new, breakthrough ideas for creating cleaner, more efficient, and economically viable grid technologies. The challenge also aimed to accelerate the adoption of smart grid technologies.
Genius, according to their website, is "the world's biggest collection of song lyrics and crowdsourced musical knowledge." It was previously referred to as Rap Exegesis and Rap Genius to decode complex rap lyrics. Now their mission is to "annotate the world".
Google Image Labeler was a sort of game where users were asked to label pictures to improve images search results.
Gooseberry Patch, has been using crowdsourcing to create their community-style cookbooks since 1992. Friends, buyers, fans, sales people are all encouraged to submit a recipe. Each contributors' recipe that is selected is recognized in the book and receives a free copy.
The Great War Archive was a 2008 project, led by the University of Oxford. It requested members of the general public to digitize any artifacts they held relating to the First World War and upload them to a purpose-built website. The project successfully released over 6500 items and stories online, which can be freely downloaded and used for education and research. The project was funded by the Joint Information Systems Committee. In 2011, the team at the University of Oxford received further funding from Europeana to run a similar crowdsourcing initiative in Germany. From 2012, Europeana extended the project to become a project called "Europeana 1914–1918", a collaboration led by Europeana, with support from the team at the University of Oxford. There is a website where the project encourages the public from all European Union states to contribute information about World War I, especially their family's stories and digitized photographs of their artifacts.
The Guardian's investigation into the MP Expense Scandal in the United Kingdom. The newspaper created a system to allow the public to search methodically through 700,000 expense-claim documents. Over 20,000 people participated in finding erroneous and remarkable expense claims by members of parliament.
