Other creators rose to fame after the platform merged with on 2 August 2018. [ 101 ]One notable TikTok trend is the ” hit or miss ” meme, which began from a snippet of iLOVEFRiDAY’s tuy nhiên ” Mia Khalifa. ” The tuy nhiên has been used in over four million TikTok videos and helped introduce the app to a larger Western audience. [ 102 ] [ 103 ] TikTok also played a major part in making ” Old Town Road ” by Lil Nas X one of the biggest songs of 2019 and the longest running number-one tuy nhiên in the history of the Billboard Hot 100. [ 104 ] [ 105 ] [ 106 ]TikTok has allowed many other bands to gain a wider audience, often including foreign fans.

TikTok has banned Holocaust denial, but other conspiracy theories have become popular on the platform, such as Pizzagate and QAnon (two conspiracy theories popular among the U.S. alt-right) whose hashtags reached almost 80 million views and 50 million views respectively by June 2020.[112] The platform has also been used to spread misinformation about the COVID-19 pandemic, such as clips from Plandemic.[112] TikTok removed some of these videos, and has generally added links to accurate COVID-19 information on videos with tags related to the pandemic.[113]

On 10 August 2020, Emily Jacobssen wrote and sang “Ode To Remy,” a song praising the protagonist from Pixar’s 2007 computer-animated film named Ratatouille.

Influencer marketing

TikTok has provided a platform for users to create content not only for fun, but also for money. As the platform has grown significantly over the past few years, it has allowed companies to advertise and rapidly reach their intended demographic through influencer marketing. [ 124 ] The platform’s AI algorithm also contributes to the influencer marketing potential, as it picks out content according to the user’s preference. [ 125 ] Sponsored content is not as prevalent on the platform as it is on other social truyền thông apps, but brands and influencers still can make as much as they would if not more in comparison to other platforms.

Use by businesses

[ 130 ]Some small businesses have used TikTok to advertise and to reach an audience wider than the geographical region they would normally serve. The viral response to many small business TikTok videos has been attributed to TikTok’s algorithm, which shows content that viewers at large are drawn to, but which they are unlikely to actively search for ( such as videos on unconventional types of businesses, like beekeeping and logging ). [ 131 ]In 2020, digital truyền thông companies such as Group Nine Media and Global used TikTok increasingly, focusing on tactics such as brokering partnerships with TikTok influencers and developing branded content campaigns. [ 132 ] Notable collaborations between larger brands and top TikTok influencers have included Chipotle ‘ s partnership with David Dobrik in May 2019 [ 133 ] and Dunkin ‘ Donuts ‘ partnership with Charli D’Amelio in September 2020.

Country bans and attempted bans

Nước Trung Hoa

In April 2020, TikTok officially cooperated with mainland China’s Internet censorship mechanism and began to prohibit the use of overseas versions of Douyin in mainland Trung Quốc. Different from general blockade, TikTok adopted an IP lock zone, mainly for mainland Trung Quốc ; Hong Kong and Macau were not affected. The direct consequence of the lock zone is that Chinese users cannot log in to TikTok using a VPN. Officials have also restricted the numbers of China Mobile, China Telecom and Trung Quốc Unicom. The phone numbers of the above three cannot log in to TikTok. Even so, there are a large number of cracked versions of TikTok on the Chinese Internet. The cracked version of TikTok can watch videos normally, but the phone number restriction has not been cracked and users cannot log in .In January 2021, the Great Firewall of China’s blocking measures on TikTok were further upgraded, and the monitoring of the cracked version of TikTok was increased, and measures such as node blocking and IP blocking were adopted to interfere with the normal watching of videos by mainland users : that is, users watch normally, but after a few videos, the video cannot be refreshed, and you need to re-enter the software before you can continue watching .The official website of the overseas version of TikTok is currently blocked by the Great Firewall, and the Chinese language of the official website of the overseas version only provides Traditional Chinese, as officially used in Taiwan, Hong Kong and Macau, instead of Simplified Chinese .


Iranians can not access TikTok because of both TikTok rules and Iranian censor. [ 136 ]


The Indian Government banned TikTok along with 58 other mobile apps with Chinese developers or investors, including WeChat, UC Browser and PUBG on 29 June 2020. [ 137 ] [ 138 ] The Ministry of Electronics and Information Technology released a statement saying the apps were ” prejudicial to sovereignty and integrity of India, defence of India, security of state and public order. ” [ 139 ] [ 138 ] It was extended to 47 other apps which the ministry claimed were clones or variants of the banned apps. [ 138 ] The ban on TikTok and the 58 other apps was made permanent in January 2021. [ 140 ] In February 2021, TikTok announced that due to the ban it will be forced to lay off over 2,000 employees in India. [ 141 ]

United States

On 6 August 2020, then U.S. President Donald Trump signed an order[142][143] which would ban TikTok transactions in 45 days if it was not sold by ByteDance. Trump also signed a similar order against the WeChat application owned by the Chinese multinational company Tencent.[144][43]

On 14 August 2020, Trump issued another order [ 145 ] [ 146 ] giving ByteDance 90 days to sell or spin off its U.S. TikTok business. [ 147 ] In the order, Trump said that there is ” credible evidence ” that leads him to believe that ByteDance ” might take action that threatens to impair the national security of the United States. ” [ 148 ] Donald Trump was concerned about TikTok being a threat because TikTok’s parent company was rumored to be taking United States user data and reporting it back to Chinese operations through the company ByteDance. [ 149 ] As of 2021, there is still the fear that TikTok is not protecting the privacy of its users and may be giving their data away. [ 150 ]TikTok considered selling the American portion of its business, and held talks with companies including Microsoft, Walmart, and Oracle. [ 151 ]

On 18 September, TikTok filed a lawsuit, TikTok v. Trump. On 23 September 2020, TikTok filed a request for a preliminary injunction to prevent the app from being banned by the Trump administration.[152] U.S. judge Carl J. Nichols temporarily blocked the Trump administration order that would effectively ban TikTok from being downloaded in U.S. app stores starting midnight on 27 September 2020. Nichols allowed the app to remain available in the U.S. app stores, but declined to block the additional Commerce Department restrictions that could have a larger impact on TikTok’s operations in the U.S. These restrictions were set to take place 12 November 2020.[153]

Three TikTok influencers filed a lawsuit, Marland v. Trump.[154] On 30 October, Pennsylvania judge Wendy Beetlestone ruled against the Commerce Department, blocking them from restricting TikTok.[154] On 12 November, the Commerce Department stated that it would obey the Pennsylvania ruling and that it would not try to enforce the restrictions against TikTok that had been scheduled for 12 November.[154]

The Commerce Department appealed the original ruling in TikTok v. Trump. On 7 December, Washington D.C. district court judge Carl J. Nichols issued a preliminary injunction against the Commerce Department, preventing them from imposing restrictions on TikTok.[155][156][157]

In June 2021, new president Joe Biden signed an executive order revoking the Trump administration ban on TikTok, and instead ordered the Secretary of Commerce to investigate the app to determine if it poses a threat to U.S. national security. [ 158 ]

Indonesia and Bangladesh

TikTok has been intermittently blocked in Indonesia and Bangladesh on different bases. [ 159 ] [ 160 ]


On 11 October 2020, Pakistan became the next country to ban the social media platform after not complying with issues regarding the content on the platform brought up by their government.[161] TikTok representatives are currently[when?] speaking with Pakistani officials in hopes of building better relations and allowing the people of Pakistan to create on the platform.[161]


In response to the 2022 Russian invasion of Ukraine, TikTok banned new Russian posts and livestreams. [ 162 ] [ 163 ] [ 164 ]


Addiction concerns

Some users may find it hard to stop using TikTok. [ 165 ] In April 2018, an addiction-reduction feature was added to Douyin. [ 165 ] This encouraged users to take a break every 90 minutes. [ 165 ] Later in 2018, the feature was rolled out to the TikTok app. TikTok uses some top influencers such as Gabe Erwin, Alan Chikin Chow, James Henry, and Cosette Rinab to encourage viewers to stop using the app and take a break. [ 166 ]Many were also concerned with users ‘ attention spans with these videos. Users watch short 15 – second clips repeatedly and studies say that this could result in a decreased attention span. This is a concern as many of TikTok’s audience are younger children, whose brains are still developing. [ 167 ] Tiktok executives và representatives have noted and made aware to advertisers on the platform that users have poor attention spans. With the large amount of video content, nearly 50 % of users find it stressful to watch a video longer than a minute and a third of users watch videos at double speed. [ 129 ]

Content concerns

Some countries have shown concerns regarding the content on TikTok, as their cultures view it as obscene, immoral, vulgar, and encouraging pornography. There have been temporary blocks and warnings issued by countries including Indonesia, [ 159 ] Bangladesh, [ 160 ] India, [ 168 ] and Pakistan [ 169 ] [ 170 ] over the content concerns. In 2018, Douyin was reprimanded by Chinese truyền thông watchdogs for showing ” unacceptable ” content. [ 171 ]On 27 July 2020, Egypt sentenced five women to two years in prison over TikTok videos. One of the women had encouraged other women to try and earn money on the platform, another woman was sent to prison for dancing. The court also imposed a fine of 300,000 Egyptian pounds ( UK £ 14,600 ) on each defendant. [ 172 ]Concerns have been voiced regarding content relating to, and the promotion and spreading of, hateful words and far-right extremism, such as anti-semitism, racism, and xenophobia. Some videos were shown to expressly deny the existence of the Holocaust and told viewers to take up arms and fight in the name of white supremacy and the swastika. [ 173 ] As TikTok has gained popularity among young children, [ 174 ] and the popularity of extremist and hateful content is growing, calls for tighter restrictions on their flexible boundaries have been made. TikTok have since released tougher parental controls to filter out inappropriate content and to ensure they can provide sufficient protection and security. [ 175 ]A viral TikTok trend known as ” devious licks ” involves students vandalizing or stealing school property and posting the videos of the action on the platform. The trend has led to increasing school vandalism and subsequent measures taken by some schools to prevent damage. Some students have been arrested for participating in the trend. [ 176 ] [ 177 ] TikTok has taken measures to remove and prevent access to content displaying the trend. [ 178 ]

The Wall Street Journal has reported that doctors experienced a surge in reported cases of tics, tied to an increasing number of TikTok videos from content creators with Tourette syndrome. Doctors suggested that the cause may be a social one as users who consumed content showcasing various tics would sometimes develop tics of their own.[179]

In March 2022, the Washington Post reported that Facebook owner Meta Platforms had paid Targeted Victory—a consulting firm backed by supporters of the U.S. Republican Party—to coordinate lobbying and media campaigns against TikTok to portray it as “a danger to American children and society”, primarily to counter criticism of Facebook’s own services. This included op-eds and letters to the editor in regional publications, the amplification of “dubious local news stories citing TikTok as the origin of dangerous teen trends” (such as the aforementioned “devious licks”, and an alleged “Slap a Teacher” challenge), including those whose initial development actually began on Facebook, and the similar promotion of “proactive coverage” of Facebook corporate initiatives.[180]
