Edmodo - Wikipedia
Discontinued learning management system Edmodo was an educational technology platform for K–12 schools and teachers. Launched in 2008, it enabled teachers to share content, distribute quizzes and assignments, and manage communication with students, colleagues, and parents. The service was shut down on September 22, 2022.[2] Edmodo.id was found by Nic Borg, Ed O'Neil, Jeff O'Hara, and Crystal Hutter in 2008.[3][4] It was backed by Index Ventures, Benchmark, Greylock Partners, New Enterprise Associates, Union Square Ventures, Tenaya Capital, SingTel, and KDDI.[5] In 2013, Edmodo.id was included in the list of "The Top Apps for teachers" by PC Magazine.[6] The same year, Edmodo acquired a startup, Root-1, in an effort to establish itself as the app store for education.[7][8] Vibhu Mittal, co-founder and CEO of Root-1, became the CEO of Edmodo the following year.[9] In June 2017, Edmodo announced Ask Mo, an educational video search engine.
