On this day:
YouTube is an American video-sharing website headquartered in San Bruno, California. The service was created by three former PayPal employees—Chad Hurley, Steve Chen, and Jawed Karim—in February 2005. In November 2006, it was bought by Google for US$1.65 billion. YouTube now operates as one of Google’s subsidiaries. The site allows users to upload, view, rate, share, add to favorites, report and comment on videos, and it makes use of WebM, H.264/MPEG-4 AVC, and Adobe Flash Video technology to display a wide variety of user-generated and corporate media videos. Available content includes video clips, TV show clips, music videos, short and documentary films, audio recordings, movie trailers and other content such as video blogging, short original videos, and educational videos.
Most of the content on YouTube has been uploaded by individuals, but media corporations including CBS, the BBC, Vevo, and Hulu offer some of their material via YouTube as part of the YouTube partnership program. Unregistered users can only watch videos on the site, while registered users are permitted to upload an unlimited number of videos and add comments to videos. Videos deemed potentially offensive are available only to registered users affirming themselves to be at least 18 years old. In December 2016, the website was ranked as the second most popular site by Alexa Internet, a web traffic analysis company.
YouTube earns advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Red, a subscription service offering ad-free access to the website and access to exclusive content made in partnership with existing users.
Born in this day:
1838 – Margaret E. Knight, American inventor (d. 1914)
Margaret E. Knight (February 14, 1838 – October 12, 1914) was an American inventor, notably of the flat-bottomed paper bag. She has been called “the most famous 19th-century woman inventor”.
Margaret Knight was born on February 14th, 1838 in York, Maine to James Knight and Hannah Teal. Her father died when she was a little girl. She received a basic education, but had to leave school at 12 in order to work at a cotton mill for several years.
In 1868, while living in Springfield, Massachusetts, Knight invented a machine that folded and glued paper to form the flat-bottomed brown paper bags familiar to shoppers today. Knight built a wooden model of the device, but needed a working iron model to apply for a patent. Charles Annan, who was in the machine shop where Knight’s iron model was being built, stole her design and patented the device. Knight filed a successful patent interference lawsuit and was awarded the patent in 1871. With a Massachusetts business partner, Knight established the Eastern Paper Bag Co. and received royalties.
Her many other inventions included a numbering machine, a window frame and sash, patented in 1894, and several devices relating to rotary engines, patented between 1902 and 1915.
Later life and legacy
Knight was awarded the Decoration of the Royal Legion of Honour by Queen Victoria in 1871.[better source needed]
Knight never married and died on October 12, 1914 at the age of 76.
A plaque recognizing her as the “first woman awarded a U.S. patent” and holder of 87 U.S. patents hangs on the Curry Cottage at 287 Hollis St in Framingham. However, Knight was not actually the first: either Mary Kies or Hannah Slater has that honour.
Knight was inducted into the National Inventors Hall of Fame in 2006. The original bag-making machine is in the Smithsonian Museum in Washington, D.C..
