Hashtags
A hashtag is a metadata tag that is prefaced by the hash (also known as pound or octothorpe) sign, ''#''. On social media, hashtags are used on microblogging and photo-sharing services such as Twitter or Instagram as a form of user-generated tagging that enables cross-referencing of content by topic or theme. For example, a search within Instagram for the hashtag ''#bluesky'' returns all posts that have been tagged with that term. After the initial hash symbol, a hashtag may include letters, numerals, or underscores. The use of hashtags was first proposed by American blogger and product consultant Chris Messina in a 2007 tweet. Messina made no attempt to patent the use because he felt that "they were born of the internet, and owned by no one". Hashtags became entrenched in the culture of Twitter and soon emerged across Instagram, Facebook, and YouTube. In June 2014, ''hashtag'' was added to the ''Oxford English Dictionary'' as "a word or phrase with the symbol ''#'' in front o ...

Instagram
Instagram is a photo and video sharing social networking service owned by American company Meta Platforms. The app allows users to upload media that can be edited with filters and organized by hashtags and geographical tagging. Posts can be shared publicly or with preapproved followers. Users can browse other users' content by tag and location, view trending content, like photos, and follow other users to add their content to a personal feed.

In 2015, this restriction was eased with an increase to 1080 pixels. It also added messaging features, the ability to include multiple images or videos in a single post, and a Stories feature—similar to its main competitor Snapchat—which allowed users to post their content to a sequential feed, with each post accessible to others for 24 hours.

Chris Messina (open-source Advocate)
Christopher Reaves Messina (born January 7, 1981) is an American blogger, product consultant and speaker who is the inventor of the hashtag as it is currently used on social media platforms. In a 2007 tweet, Messina proposed vertical/associational grouping of messages, trends, and events on Twitter by the means of hashtags. The hashtag was intended to be a type of metadata tag that allowed users to apply dynamic, user-generated tagging, which made it possible for others to easily find messages with a specific theme or content. It allowed easy, informal markup of folksonomy without need of any formal taxonomy or markup language. Hashtags have since been referred to as the "eavesdroppers", "wormholes", "time-machines", and "veins" of the Internet. Although Twitter's initial response to Messina's proposed use of hashtags was negative "these things are for nerds" a series of events, including the devastating fire in San Diego County later that year, saw the first widespread use ...

Tag (metadata)
In information systems, a tag is a keyword or term assigned to a piece of information (such as an Internet bookmark, multimedia, database record, or computer file). This kind of metadata helps describe an item and allows it to be found again by browsing or searching. Tags are generally chosen informally and personally by the item's creator or by its viewer, depending on the system, although they may also be chosen from a controlled vocabulary. Tagging was popularized by websites associated with Web 2.0 and is an important feature of many Web 2.0 services. It is now also part of other database systems, desktop applications, and operating systems. Overview People use tags to aid classification, mark ownership, note boundaries, and indicate online identity. Tags may take the form of words, images, or other identifying marks.
