YouTube-funded and Subbable periods (2011–2014) The
Crash Course YouTube channel was conceived by the Green Brothers after YouTube approached them with an opportunity to launch one of the initial YouTube-funded channels as part of the platform's
original channel initiative. The channel was teased in December 2011, and then launched on January 26, 2012, with the first episode of its
World History series, hosted by John Green. The episode covered the
Agricultural Revolution, and a new episode aired on YouTube every Thursday through November 9, 2012. Hank Green's first series,
Crash Course Biology, then launched on January 30, 2012, with its first episode covering carbon. A new episode aired on YouTube every Monday until October 22 of that year. The brothers would then go on to end 2012 with two shorter series, with John and Hank teaching English literature and ecology, respectively. Following their launch year, John and Hank returned in 2013 with
US History and
Chemistry, respectively. However, that April, John detailed that
Crash Course was going through financial hardships; in July, Hank uploaded a video titled "A Chat with YouTube", in which he expressed his frustration with the ways YouTube had been changing and controlling its website. Eventually, YouTube's original channel initiative funding ran out, and shortly after Hank's video, the Green brothers decided to launch
Subbable, a
crowdfunding website where viewers could donate monthly to channels in exchange for perks. On launching Subbable, Hank Green stated: "We ascribe to the idealistic notion that audiences don't pay for things because they have to[,] but because they care about the stuff that they love and want it to continue to grow". In March 2015, Subbable was acquired by
Patreon, and
Crash Course's crowdfunding moved over as part of the acquisition. In May 2014, John mentioned an upcoming 10-episode
Crash Course season on
Big History, funded by a grant from one of
Bill Gates's organizations. The series outlined the history of existence, from the Big Bang forward into the evolution of life. Both Green brothers hosted the series, with
Emily Graslie also participating as a guest host.
Partnership with PBS Digital Studios (2014–2017) , host of
US Government and Politics, was brought on as part of the
PBS Digital Studios funding deal. In 2014,
Crash Course announced a partnership with
PBS Digital Studios, which began in 2015 with the
Astronomy and
US Government and Politics series. In addition to funding the channel itself, the partnership also entails PBS Digital Studios helping
Crash Course to receive sponsorships. As a result of the partnership as well as John commencing a year-long hiatus from the show in 2015, additional hosts were added to increase the number of concurrent series. Though the partnership meant PBS Digital Studios would assist with the production of
Crash Course, the channel continued to receive funding from its audience through
Patreon. In April 2015,
The Guardian reported that
Crash Course received $25,900 per month through Patreon donations. The series was hosted by
Sabrina Cruz, known on YouTube as Answer in Progress. On October 12, 2016, the
Crash Course YouTube channel uploaded a preview for
Crash Course Human Geography. Hosted by Miriam Nielsen, the course was to discuss "what
Human Geography isn't, and what it is, and discuss humans in the context of their world." Two episodes were posted during each of the following two weeks; however, the videos were removed on October 27, with John Green stating on Twitter that "...we got important things wrong. We'll rework the series... And we'll bring a better series to you in a few months." On October 31, John further explained that the videos were removed due to "factual mistakes as well as too strident a tone," and that the mishap was caused by a rushed production stemming from a lack of staffing and budgeting. The following October, during an "Ask Me Anything" (AMA) session on
Reddit, John indicated the course may not return for some time, noting that "we don't feel like we've cracked it yet." The channel would go on to launch their
Geography course in November 2020, intended to cover both physical and human geography over its run. In 2017,
Crash Course launched three film-related series: one covered
film history, another
film production, and the last of which covered
film criticism. Also in 2017, Thomas Frank began hosting
Crash Course Study Skills, which covered topics such as productivity skills, time management, and note-taking.
Complexly branding and YouTube Learning Fund (2018–2019) hosted
Business: Entrepreneurship in 2019. Starting with the
Statistics course in early 2018,
Crash Course series that are not PBS co-productions began to directly identify as
Complexly productions. Also that year,
Crash Course launched an
Arabic-language edition of
World History hosted by Yasser Abumuailek and produced by
Deutsche Welle (DW), which was uploaded to DW's Arabic YouTube channel. In July 2018, YouTube announced its YouTube Learning initiative, dedicated to supporting educational content on the platform. A few months later, as $20 million was invested into expanding the initiative,
Crash Course secured additional funding via the initiative's Learning Fund program. However, PBS Digital Studios remained one of the primary sources of funding
Crash Course, and the network also continued to help in finding sponsorships for the show. In July, YouTube launched Learning Playlists as a continuation of their Learning Fund initiative; while videos in Learning Playlists notably lack recommended videos attached to them, in contrast to videos included in regular playlists on YouTube,
Partnership with Arizona State University (2020–present) A collaboration with
Arizona State University (ASU) titled
Study Hall was announced in March 2020, which includes less structured learning in its topics. It was hosted by ASU alumni and advised by their faculty, with episodes posted on the university's YouTube channel but production and visual design by Complexly in the Crash Course style. The partnership was renewed in 2022, with two new series premiering: Fast Guides is appearing on a new dedicated Study Hall channel, focusing on showing what students can expect to study in a given
major; and How to College on the main Crash Course channel, showing the process of choosing, applying for, and starting at a given institution. In January 2023,
Crash Course announced that they would be offering college courses on YouTube, in continued partnership with ASU and Google. The course content would be available online for free, with the full online course available through ASU for , which would be led by ASU faculty and include direct interaction. Students would then have the option to spend to receive college credit for the course that would be transferable to any institution that accepts ASU credits. ==Production==
