ChuChu learns many lessons from parents, who provide the company with constant feedback. It heard from parents who questioned the diversity of its characters, who were all light-skinned; it now has two light-skinned and two dark-skinned main characters. It heard from parents who wondered about the toy guns in one video; it removed them. It heard from parents about an earlier version of the “Johny Johny” video, in which the little boy sleeps in a communal bed with his family, as is common in India; in a new version, he has his own room.
In March 2017, the government of the United Kingdom pulled its advertising campaigns from YouTube, after reports that its ads had appeared on videos containing extremism content. The government demanded assurances that its advertising would "be delivered in a safe and appropriate way". The Guardian newspaper, as well as other major British and U.S. brands, similarly suspended their advertising on YouTube in response to their advertising appearing near offensive content. Google stated that it had "begun an extensive review of our advertising policies and have made a public commitment to put in place changes that give brands more control over where their ads appear". In early April 2017, the YouTube channel h3h3Productions presented evidence claiming that a Wall Street Journal article had fabricated screenshots showing major brand advertising on an offensive video containing Johnny Rebel music overlaid on a Chief Keef music video, citing that the video itself had not earned any ad revenue for the uploader. The video was retracted after it was found that the ads had actually been triggered by the use of copyrighted content in the video.
All the estimates by research firms and analysts, says Kirjner, are "based more on belief and anecdotes than on truly representative data. What's more -- beyond anecdotes either shared by Google or collected through discussions with ad buyers, creators and multichannel network operators -- we know very little about what is available on YouTube, what people watch and how much it gets watched."
ChuChu has changed over time—it has slowed the pacing of its videos, focused on the key elements of scenes, and made more explicitly educational videos. But in the wilds of YouTube, the videos with the most views, not the most educational value, are the ones that rise to the top. ChuChu’s newer videos, which have more of the features Johnson looks for, have not had the time to hoover up as much attention, so the old ones keep appearing in YouTube searches and suggestions.
Karim said the inspiration for YouTube first came from Janet Jackson's role in the 2004 Super Bowl incident, when her breast was exposed during her performance, and later from the 2004 Indian Ocean tsunami. Karim could not easily find video clips of either event online, which led to the idea of a video sharing site. Hurley and Chen said that the original idea for YouTube was a video version of an online dating service, and had been influenced by the website Hot or Not.
