On 9 November 2017, TikTok's parent company, ByteDance, spent up to U.S. $1 billion to purchase musical.ly, a startup headquartered in Shanghai with an overseas office in Santa Monica, California, U.S. Musical.ly was a social media video platform that allowed users to create short lip-sync and comedy videos, initially released in August 2014. It was well known, especially to the younger audience. Looking forward to leveraging the U.S. digital platform's young user base, TikTok merged with musical.ly on 2 August 2018 to create a larger video community, with existing accounts and data consolidated into one app, keeping the title TikTok. This ended musical.ly and made TikTok a worldwide app, excluding China, since China already has Douyin.
TikTok and Douyin have almost the same user interface but no access to each other's content. Their servers are each based in the market where the respective app is available. The two products are similar, but features are not identical. Douyin includes an in-video search feature that can search by people's faces for more videos of them and other features such as buying, booking hotels and making geo-tagged reviews. Since its launch in 2016, TikTok and Douyin rapidly gained popularity in virtually all parts of the world. TikTok surpassed 2 billion mobile downloads worldwide in October 2020.
Douyin was launched by ByteDance in Beijing, China in September 2016, originally under the name A.me, before rebranding to Douyin (抖音) in December 2016. ByteDance planned on Douyin expanding overseas. The founder of ByteDance, Zhang Yiming, stated that "China is home to only one-fifth of Internet users globally. If we don’t expand on a global scale, we are bound to lose to peers eyeing the four-fifths. So, going global is a must." Douyin was developed in 200 days and within a year had 100 million users, with more than one billion videos viewed every day.
TikTok, known in China as Douyin (Chinese: 抖音; pinyin: Dǒuyīn), is a Chinese short-form video hosting service owned by ByteDance Ltd. It hosts a variety of short-form user videos, from genres like pranks, stunts, tricks, jokes, dance, and entertainment with durations from 15 seconds to ten minutes. TikTok is an international version of Douyin, which was originally released in the Chinese market in September 2016. TikTok was launched in 2017 for iOS and Android in most markets outside of mainland China; however, it became available worldwide only after merging with another Chinese social media service, Musical.ly, on 2 August 2018.
The app was launched as TikTok in the international market in September 2017. On 23 January 2018, the TikTok app ranked first among free application downloads on app stores in Thailand and other countries.
After merging with musical.ly in August, downloads increased and TikTok became the most downloaded app in the U.S. in October 2018, which musical.ly had done once before. In February 2019, TikTok, together with Douyin, hit one billion downloads globally, excluding Android installs in China. In 2019, media outlets cited TikTok as the 7th-most-downloaded mobile app of the decade, from 2010 to 2019. It was also the most-downloaded app on Apple's App Store in 2018 and 2019, surpassing Facebook, YouTube and Instagram. In September 2020, a deal was confirmed between ByteDance and Oracle in which the latter will serve as a partner to provide cloud hosting. Walmart intends to invest in TikTok. This deal would stall in 2021 as newly elected President Biden's Justice Department put a hold on the previous U.S. ban under President Trump. In November 2020, TikTok signed a licensing deal with Sony Music. In December 2020, Warner Music Group signed a licensing deal with TikTok. In April 2021, Abu Dhabi's department of Culture and Tourism partnered with TikTok to promote tourism. It came following the January 2021 winter campaign, initiated through a partnership between the UAE Government Media Office partnered and TikTok to promote the country's tourism.
In the United States, celebrities, including Jimmy Fallon and Tony Hawk, began using the app in 2018. Other celebrities, including Jennifer Lopez, Jessica Alba, Will Smith, and Justin Bieber joined TikTok as well and many other celebrities have followed.
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, Bangladesh, India, and Pakistan over the content concerns. In 2018, Douyin was reprimanded by Chinese media watchdogs for showing "unacceptable" content.
There are concerns that some users may find it hard to stop using TikTok. In April 2018, an addiction-reduction feature was added to Douyin. This encouraged users to take a break every 90 minutes. 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.
Tencent's WeChat platform has been accused of blocking Douyin's videos. In April 2018, Douyin sued Tencent and accused it of spreading false and damaging information on its WeChat platform, demanding CN¥1 million in compensation and an apology. In June 2018, Tencent filed a lawsuit against Toutiao and Douyin in a Beijing court, alleging they had repeatedly defamed Tencent with negative news and damaged its reputation, seeking a nominal sum of CN¥1 in compensation and a public apology. In response, Toutiao filed a complaint the following day against Tencent for allegedly unfair competition and asking for CN¥90 million in economic losses.
The app has spawned numerous viral trends, Internet celebrities, and music trends around the world. Many stars got their start on musical.ly, which merged with TikTok on 2 August 2018. These users include Loren Gray, Baby Ariel, Kristen Hancher, Zach King, Lisa and Lena, Jacob Sartorius, and many others. Loren Gray remained the most-followed individual on TikTok until Charli D’Amelio surpassed her on 25 March 2020. Gray's was the first TikTok account to reach 40 million followers on the platform. She was surpassed with 41.3 million followers. D'Amelio was the first to ever reach 50, 60, and 70 million followers. Until now Charli D’Amelio remains the most-followed individual on the platform. Other creators rose to fame after the platform merged with musical.ly on 2 August 2018.
In February 2019, the United Kingdom's Information Commissioner's Office launched an investigation of TikTok following the fine ByteDance received from the United States Federal Trade Commission (FTC). Speaking to a parliamentary committee, Information Commissioner Elizabeth Denham said that the investigation focuses on the issues of private data collection, the kind of videos collected and shared by children online, as well as the platform's open messaging system which allows any adult to message any child. She noted that the company was potentially violating the General Data Protection Regulation (GDPR) which requires the company to provide different services and different protections for children.
On 27 February 2019, the United States Federal Trade Commission (FTC) fined ByteDance U.S.$5.7 million for collecting information from minors under the age of 13 in violation of the Children's Online Privacy Protection Act. ByteDance responded by adding a kids-only mode to TikTok which blocks the upload of videos, the building of user profiles, direct messaging, and commenting on others' videos, while still allowing the viewing and recording of content. In May 2020, an advocacy group filed a complaint with the FTC saying that TikTok had violated the terms of the February 2019 consent decree, which sparked subsequent Congressional calls for a renewed FTC investigation. In July 2020, it was reported that the FTC and the United States Department of Justice had initiated investigations.
In 2020, digital media 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. Notable collaborations between larger brands and top TikTok influencers have included Chipotle's partnership with David Dobrik in May 2019 and Dunkin' Donuts' partnership with Charli D'Amelio in September 2020.
Trends are shown on TikTok's explore page or the page with the search logo. The page enlists the trending hashtags and challenges among the app. Some include #posechallenge, #filterswitch, #dontjudgemechallenge, #homedecor, #hitormiss, #bottlecapchallenge and more. In June 2019, the company introduced the hashtag #EduTok which received 37 billion views. Following this development, the company initiated partnerships with edtech startups to create educational content on the platform.
On 3 September 2019, TikTok and the U.S. National Football League (NFL) announced a multi-year partnership. The agreement occurred just two days before the NFL's 100th season kick-off at Soldier Field, where TikTok hosted activities for fans in honor of the deal. The partnership entails the launch of an official NFL TikTok account, which is to bring about new marketing opportunities such as sponsored videos and hashtag challenges.

In November 2019, a class action lawsuit was filed in California that alleged that TikTok transferred personally identifiable information of U.S. persons to servers located in China owned by Tencent and Alibaba. The lawsuit also accused ByteDance, TikTok's parent company, of taking user content without their permission. The plaintiff of the lawsuit, college student Misty Hong, downloaded the app but said she never created an account. She realized a few months later that TikTok has created an account for her using her information (such as biometric) and made a summary of her information. The lawsuit also alleged that information was sent to Chinese tech giant Baidu. In July 2020, twenty lawsuits against TikTok were merged into a single class action lawsuit in the United States District Court for the Northern District of Illinois. In February 2021, TikTok agreed to pay $92 million to settle the class action lawsuit.
Several users have reported endemic cyberbullying on TikTok, including racism and ableism. In December 2019, following a report by German digital rights group Netzpolitik.org, TikTok admitted that it had suppressed videos by disabled users as well as LGBTQ+ users in a purported effort to limit cyberbullying. TikTok's moderators were also told to suppress users with "abnormal body shape," "ugly facial looks," "too many wrinkles," or in "slums, rural fields" and "dilapidated housing" to prevent bullying.
Since 2014, the only apps with more than 3 billion downloads are WhatsApp, Instagram, and Messenger, and all of these apps belong to Facebook. TikTok is also the first non-Facebook app to be downloaded more than 3 billion times. App market research firm Sensor Tower pointed out in July that although TikTok has been banned in India, its largest market, since June, downloads in the rest of the world continue to increase, reaching 3 billion downloads in 2020.
TikTok has allowed many other bands to gain a wider audience, often including foreign fans. For example, despite never having toured in Asia, the band Fitz and the Tantrums developed a large following in South Korea following the widespread popularity of their song "HandClap" on the platform. "Any Song" by R&B and rap artist Zico became number one on the Korean music charts due to the popularity of the #anysongchallenge, where users dance the choreography of "Any Song." The platform has received some criticism for not paying royalties to artists whose music is used on their platform. In 2020, more than 176 different songs surpassed 1 billion video views on TikTok.
In January 2020, Check Point Research discovered a security flaw in TikTok which could have allowed hackers access to user accounts using SMS. In February, Reddit CEO Steve Huffman criticised the app, calling it "spyware," and stating "I look at that app as so fundamentally parasitic, that it's always listening, the fingerprinting technology they use is truly terrifying, and I could not bring myself to install an app like that on my phone." Responding to Huffman's comments, TikTok stated, "These are baseless accusations made without a shred of evidence." Wells Fargo banned the app from its devices due to privacy and security concerns.
In January 2020, Media Matters for America said that TikTok hosted misinformation related to the COVID-19 pandemic despite a recent policy against misinformation.

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 China. Different from general blockade, TikTok adopted an IP lock zone, mainly for mainland China; 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 China 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.

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. 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.
