Coronavirus disease 2019
COVID-19 is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic.
The symptoms of COVID‑19 can vary but often include fever,[7] fatigue, cough, breathing difficulties, loss of smell, and loss of taste.[8][9][10] Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms.[11][12] Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock, or multiorgan dysfunction).[13] Older people have a higher risk of developing severe symptoms. Some complications result in death. Some people continue to experience a range of effects (long COVID) for months or years after infection, and damage to organs has been observed.[14] Multi-year studies on the long-term effects are ongoing.[15]
COVID‑19 transmission occurs when infectious particles are breathed in or come into contact with the eyes, nose, or mouth. The risk is highest when people are in close proximity, but small airborne particles containing the virus can remain suspended in the air and travel over longer distances, particularly indoors. Transmission can also occur when people touch their eyes, nose, or mouth after touching surfaces or objects that have been contaminated by the virus. People remain contagious for up to 20 days and can spread the virus even if they do not develop symptoms.[16]
Testing methods for COVID-19 to detect the virus’s nucleic acid include real-time reverse transcription polymerase chain reaction (RT‑PCR),[17][18] transcription-mediated amplification,[17][18][19] and reverse transcription loop-mediated isothermal amplification (RT‑LAMP)[17][18] from a nasopharyngeal swab.[20]
Several COVID-19 vaccines have been approved and distributed in various countries, many of which have initiated mass vaccination campaigns. Other preventive measures include physical or social distancing, quarantining, ventilation of indoor spaces, use of face masks or coverings in public, covering coughs and sneezes, hand washing, and keeping unwashed hands away from the face. While drugs have been developed to inhibit the virus, the primary treatment is still symptomatic, managing the disease through supportive care, isolation, and experimental measures.

The Founding of YouTube A Short History
YouTube is one of the most influential platforms in modern media, but its origin story is surprisingly simple: a small team wanted an easier way to share video online. In the early 2000s, uploading and sending video files was slow, formats were inconsistent, and most websites weren’t built for smooth playback. YouTube’s founders focused on removing those barriers—making video sharing as easy as sending a link.
Who Founded YouTube?
YouTube was founded by three former PayPal employees: Chad Hurley, Steve Chen, and Jawed Karim. They combined product thinking, engineering skills, and a clear user goal: create a website where anyone could upload a video and watch it instantly in a browser.
- Chad Hurley — product/design focus and early CEO role
- Steve Chen — engineering and infrastructure
- Jawed Karim — engineering and early concept support
The Problem YouTube Solved
At the time, sharing video often meant emailing huge files or dealing with complicated players and downloads. YouTube made video:
- Uploadable by non-experts (simple interface)
- Streamable in the browser (no special setup)
- Sharable through links and embedding on other sites
Early Growth and the First Video
YouTube launched publicly in 2005. One of the most famous early moments was the first uploaded video, “Me at the zoo,” featuring co-founder Jawed Karim. The clip was short and casual—exactly the kind of everyday content that proved the platform’s big idea: ordinary people could publish video without needing a studio.
Key Milestones Timeline
| 2005 | YouTube is founded and launches | Introduced easy browser-based video sharing |
| 2005 | “Me at the zoo” is uploaded | Became a symbol of user-generated video culture |
| 2006 | Google acquires YouTube | Provided resources to scale hosting and global reach |
Why Google Bought YouTube
By 2006, YouTube’s traffic was exploding. Video hosting is expensive—bandwidth and storage costs rise fast when millions of people watch content daily. Google’s acquisition gave YouTube the infrastructure and advertising ecosystem to grow into a sustainable business.
What YouTube’s Founding Changed
YouTube didn’t just create a popular website; it reshaped how people learn, entertain themselves, and build careers online. Its founding helped accelerate:
- Creator-driven media and influencer culture
- How-to education and free tutorials at massive scale
- Music discovery, commentary, and global community trends
From a small startup idea to a global video powerhouse, YouTube’s founding is a classic example of a simple product solving a real problem—and changing the internet in the process.
