The YouTube Adpocalypse is a site-wide term emerging from the March-May 2017 advertiser boycott on YouTube. The boycott arose from advertisements being played on the video, "Chief Keef dancing to Alabama N*gger", and other extremist content, leading to the UK Government, Coca-Cola, Dr. Pepper, Johnson & Johnson, and many major brands pulling their advertisements from YouTube.
In May 2017, famous American model, Kendall Jenner was featured in a YouTube Pepsi advertisement which caused criticism from the press due to the video consisting of her giving a Pepsi can to a Police Officer during a protest between Civil Rights Activists and the Police, resolving the tension between both groups. Many found the video devaluing the issue of Police brutality, specifically against Black people, by many interpreting the commercial as Police brutality and the Police interactions with the citizens around them being solved by drinking Pepsi. Due to the public outcry, Pepsi removed all future advertisements from YouTube, furthering the cycle of advertisers drifting from YouTube.
For most of the summer of 2017, ads were only featured on YouTube channels that were considered "Family Friendly". Many content creators have joked and complained about how their net worth has decreased, many in a drastic way, due to advertisements not seeing them as "Family Friendly". Smaller content creators have even left along with aspiring content creators being disengaged to being one.
Some content creators have even changed and or deleted their older videos titles, thumbnails, and even content to not be affected by YouTube's cutting out of advertisements on YouTubers' videos. Some have even changed or added content to their YouTube brand which is deemed more advertiser friendly by YouTube.
Many within the YouTube community insist that the YouTube Adpocalypse also happened because YouTube wanted to give attention and award videos and the creators behind them who were promoting a favored agenda.
A popular YouTuber, h3h3productions has proven that YouTube advertisements are more likely to go on television based channels rather than user generated ones even if both parties support or show the same agenda. Some of these companies were the ones who pulled their advertisements during the Adpocalypse.
In September 2017, the most subscribed user, PewDiePie said the "N-word" during one of his gaming streams, which many took offense to. Many news stories and articles were published shortly after about the incident as well as many YouTubers expressing themselves on the platform and other social media platforms about the situation, along with viewers of YouTube expressing their own opinions online as well.
The #PewDiePieIsOverParty was among the most tweeted hashtags at the time with many complaining about the manner. Firewatch, a game PewDiePie played on his channel, cut ties with him shortly afterwards due to the comment, which meant that he would not receive any more ad revenue from the gaming company. The company also deleted a video PewDiePie made associated with them and looks to continue in the future. The trend of gaming organizations cutting affiliations with PewDiePie along with him no longer getting money from those companies and the deletion of content featuring their games remains to be seen.
One of the main complaints of YouTubers and YouTube viewers was that PewDiePie's actions were going to make the Adpocalypse start up again, but far worse than before due to the constant uproar over the slur in the stream.
Some even accuse PewDiePie as being the reason why the Adpocalypse started in the first place due to his past of offensive language and imagery shown in his videos, especially after controversies surrounding antisemitism in multiple videos he made in early 2017. In January 2018, another controversy regarding YouTuber Logan Paul showing and reacting to a dead corpse in one of his video blogs surfaced, causing YouTube to change their policies again regarding smaller creators and restricting who can join YouTube’s Partner Program.
