Vaccine hesitancy

Internet advertising, on Facebook and elsewhere, is purchased by both public health authorities and anti-vaccination groups. In the United States, the majority of anti-vaccine Facebook advertising in December 2018 and February 2019 had been paid for one of two groups: Robert F. Kennedy Jr.'s Children's Health Defense and Stop Mandatory Vaccination. The ads targeted women and young couples and generally highlighted the alleged risks of vaccines, while asking for donations. Several anti-vaccination advertising campaigns also targeted areas where measles outbreaks were underway during this period. The impact of Facebook's subsequent advertising policy changes has not been studied.

The videos will then be stored online and can be shared to various social networking sites like Twitter, Facebook and YouTube. Videos will be stored on the servers and can be watched from both the mobile devices and the website. Practical online video hosting and video streaming was made possible by advances in video compression, due to the impractically high bandwidth requirements of uncompressed video. Raw uncompressed digital video has a bit rate of 168Mbps for SD video, and over 1Gbps for FHD video.

NASA Social

These events are targeted at the social media followers of NASA through platforms such as Twitter, Facebook, Google Plus, Instagram, YouTube and more. They provide guests with VIP access to NASA facilities and speakers with the goal of leveraging participants' social networks to further the outreach requirements of NASA as laid out in the National Aeronautics and Space Act. NASA re-branded these events as "Socials" in March 2012 as it expanded participation to services beyond just Twitter. As of 2015, all NASA field centers and NASA Headquarters have hosted NASA Tweetup/Social events. There were 5 NASA Tweetups in 2009, 10 in 2010, 16 in 2011, 21 in 2012, 22 in 2013, and 23 in 2014.

Android (operating system)

AndroidAndroid operating systemList of Android devices
An early prototype had a close resemblance to a BlackBerry phone, with no touchscreen and a physical QWERTY keyboard, but the arrival of 2007's Apple iPhone meant that Android "had to go back to the drawing board". Google later changed its Android specification documents to state that "Touchscreens will be supported", although "the Product was designed with the presence of discrete physical buttons as an assumption, therefore a touchscreen cannot completely replace physical buttons". By 2008, both Nokia and BlackBerry announced touch-based smartphones to rival the iPhone 3G, and Android's focus eventually switched to just touchscreens.

Friending and following

On Facebook, for example, one's "friends" have the privilege of viewing and posting to one's "timeline". Following is a similar concept on other social network services, such as Twitter and Instagram, where a person (follower) chooses to add content from a person or page to his or her newsfeed. Unlike friending, following is not necessarily mutual, and a person can unfollow (stop following) another user at any time without affecting that user's following status.

The system's user interface takes the form of a dashboard, and supports social network integrations for Twitter, Facebook, Instagram, LinkedIn, Google+ and YouTube. Additional integrations are available via Hootsuite's App Directory, including Reddit, Storify, Tumblr, and Marketo. Based in Vancouver, Hootsuite has close to 1,000 staff members in 13 locations, including Toronto, Bucharest and Mexico City. The company has more than 16 million users in over 175 countries. In 2008, Holmes needed a tool to manage multiple social media networks at his digital services agency, Invoke Media.

Aspect ratio (image)

4:3aspect ratio16:9
It was popularized by Snapchat and is also now being adopted by Twitter and Facebook. Instagram stories are based on this aspect ratio as well. Often, screen specifications are given by their diagonal length. The following formulae can be used to find the height (h), width (w) and area (A), where r stands for ratio, written as a fraction, and d for diagonal length. This article primarily addresses the aspect ratio of images as displayed, which is more formally referred to as the display aspect ratio (DAR). In digital images, there is a distinction with the (SAR), which is the ratio of pixel dimensions.

The tweet concluded that protesters were paid to be bussed to Trump demonstrations and protest. A Twitter user then posted a photograph of two buses outside a building, claiming that those were the Anti-Trump protesters. The tweet immediately went viral on both Twitter and Facebook. Fake news can easily spread due to the speed and accessibility of modern communications technology. A CNN investigation examined exactly how fake news can start to trend. There are "bots" used by fake news publishers that make their articles appear more popular than they are. This makes it more likely for people to discover them.

Marketing buzz

buzzBuzz marketingbuzz platform
Marketing buzz originally referred to oral communication but in the age of Web 2.0, social media such as Facebook, Twitter, Instagram and YouTube are now the dominant communication channels for marketing buzz. In the 16th-early-20th centuries, nearly every town had its local weekly or monthly newspapers, and subscribed editions of larger publications were regularly carried by post riders to distant populations, where their key news stories from nearby county seat or capitols and far off cities were regularly read aloud in local taverns—which were much more a part of daily life than today's bars.

Online community

Cyber bullying, the "use of long-term aggressive, intentional, repetitive acts by one or more individuals, using electronic means, against an almost powerless victim" which has increased in frequency alongside the continued growth of web communities with an Open University study finding 38% of young people had experienced or witnessed cyber bullying. It has received significant media attention due to high-profile incidents such as the death of Amanda Todd who before her death detailed her ordeal on YouTube. A key feature of such bullying is that it allows victims to be harassed at all times, something not possible typically with physical bullying.

Image sharing

photo sharingphoto-sharingphoto
Facebook stated in 2015 that there were approximately two billion images uploaded to its service daily. In terms of image sharing, Facebook is the largest social networking service. On Facebook, people can upload and share their photo albums individually, and collaboratively with shared albums. This feature allows multiple users to upload pictures to the same album, and the album's creator has the ability to add or delete contributors. Twitter collaborated with Photobucket in developing a new photo sharing service so users can attach a picture to a tweet without depending on another application such as TwitPic or Yfrog.

Treviño's first blog post was an apology for a controversial tweet posted in June 2011 over the second Gaza flotilla, the controversy which had been revived by the appointment. Guardian US launched in September 2011, led by editor-in-chief Janine Gibson, which replaced the previous Guardian America service. After a period during which Katharine Viner served as the US editor-in-chief before taking charge of Guardian News and Media as a whole, Viner's former deputy, Lee Glendinning, was appointed to succeed her as head of the American operation at the beginning of June 2015.

Laura Loomer

Loomer had been banned from Twitter in November 2018 for hate speech against Representative Ilhan Omar, and was also banned from GoFundMe and Venmo. In May 2019, Facebook and its Instagram subsidiary banned Loomer and several other high-profile far-right extremists from using the company's services for spreading misinformation and extremism. In July 2019, Loomer, again represented by Klayman, filed a defamation lawsuit against Facebook.

Personal message

private messagingprivate messagePrivate messages
Here's the trick: The pictures and videos can be viewed for 1–10 seconds, after which they will disappear and be deleted from Snapchat's servers. Some common forms of personal messaging include Facebook messaging (sometimes referred to as "inboxing"), Twitter direct messaging, Instagram direct messaging, and snapchatting. All of these forms of personal or private messaging create a way for the user to make a private space on a usually public site. For example, most activity on Facebook is public, even if only to one's friends. Messaging or "inboxing" on Facebook allows for a private space.

Application programming interface

APIAPIsapplication programming interfaces
For example, Twitter's REST API allows developers to access core Twitter data and the Search API provides methods for developers to interact with Twitter Search and trends data. The design of an API has significant impact on its usage. The principle of information hiding describes the role of programming interfaces as enabling modular programming by hiding the implementation details of the modules so that users of modules need not understand the complexities inside the modules. Thus, the design of an API attempts to provide only the tools a user would expect.

Paul Joseph Watson

In May 2019, Facebook barred Watson from using its Facebook and Instagram services. Watson described his formative moment as when, at the age of 18, he watched The Secret Rulers of the World, a documentary in which journalist Jon Ronson accompanied Alex Jones in infiltrating Bohemian Grove in California, a location where some conspiracy theorists believe that global elites plot the New World Order. Watson, along with Jones and InfoWars as a whole, has shifted from mainly commenting on conspiracy theories such as chemtrails, the New World Order and the Illuminati, to increasingly commenting against feminism, Islam, and left-wing politics.


Instagram has over 53 million photos tagged with the hashtag #selfie. The word "selfie" was mentioned in Facebook status updates over 368,000 times during a one-week period in October 2013. During the same period on Twitter, the hashtag #selfie was used in more than 150,000 tweets. The pop-up museum called The Museum of Selfies is scheduled to open its doors to all selfie lovers in the year 2018 in Glendale, a suburb of Los Angeles County, California. The appeal of selfies comes from how easy they are to create and share, and the control they give people over how they present themselves.


WhatsApp MessengerWhatsApp media
WhatsApp, one of the most activated messaging apps along with other social media networks such as Facebook and Instagram were temporarily blocked, banned and had been unavailable for about two days (March 7–8, 2018) in certain parts of the country to eradicate communal violence, especially the anti-Muslim riots. This was probably the first such instance where social media platforms had been banned in Sri Lanka. The ban was finally lifted on March 14, 2018 around midnight time in Sri Lanka. The government of Uganda banned WhatsApp and Facebook, along with other social media platforms, to enforce a tax on the use of social media.
