Although streaming media involves the production and delivery of content over the Internet, it does not necessarily imply a connection between the viewer and the publisher. Streaming has a long history of interest and usage. However, only a fraction of the potential users currently have access to a streaming interface, as hardware often only provides access to Streaming Audio and some streaming services only stream limited content. Because of this, the economics and audience demographics of streaming video are not fully understood.
Streaming content is delivered from a publisher to a consumer as a continuous Delivery of Media where it is stored on the publisher’s servers, buffered, and downloaded from the server on demand. Different types of distribution modes are employed to carry the media from the publisher to the consumer.
Some types of streaming media do not require a broadcaster or content delivery network:

Streaming video refers to video content stored on a server on the Internet. Streaming content usually is not available for offline viewing, as the associated server runs on a network attached storage (NAS) device.
Streaming video delivery is more likely to be compared to file downloads. However
File downloads are usually much faster than streaming, due to the faster download speeds of modern broadband Internet connections. However, streaming video is much more likely to be compared to analog broadcast video delivery, since the video content is stored as a continuous stream of packets that are received at an Internet router and downloaded at a later time, along with other content from the same or another website. Video download speeds are also faster than streaming, due to the larger file size of most streaming video.
The total bitrate of streaming video is limited by the speed of the Internet connection and bandwidth constraints at the end user’s ISP. The consumer’s broadband connection speed does not directly affect the content delivery speed, which is controlled by the server that hosts the content. A typical 3 Mbps (Megabits per second) download speed should be able to deliver 6 Mbps (Megabits per second) of streaming video, and a 10 Mbps (Megabits per second) download speed should be able to deliver 4.5 Mbps of streaming video.
Since the streaming service is usually accessed via a web browser
The viewing environment must be sufficiently responsive to allow the user to see the streaming content without blocking the other pages on the same page or limiting the page to 2×1 or 5×1 viewports. A small delay might be acceptable in some instances, especially for streaming an interview format video, but might be unacceptable in some other situations.Streaming video can be used to deliver online advertisements, enabling the providers of a particular service to use this as part of the service. This practice is considered video advertising and is subject to ad viewing restrictions. Streaming video is also used for distribution of personal content, like photos, video or audio content. Streaming video may require licensing or payment to host the content, like an online music video. The content may also be offered as an alternative to an advertisement that is embedded in the video, enabling viewers to subscribe to the service.
Video on demand (VOD) is a form of video on demand in which subscribers are given access to a selection of content, usually a set of TV shows and movies, that are available for viewing within a certain time frame or date range. Video on demand is a popular form of video delivery which could be viewed on a television or computer monitor, but can also be viewed on mobile devices. The popularity of VOD is especially high among younger viewers, and it can offer content intended specifically for this demographic.
Programming on video services is the most common use of streaming video as of 2009, although movie releases are also increasingly streamed in some markets. These services include Netflix, which focuses on streaming film content, and is the fastest growing of the three major online video distributors. Yahoo! Screen was launched on June 18, 2013, and primarily streams content from partners including Disney, Twentieth Century Fox, Sony Pictures Entertainment, Miramax and Showtime, while Hulu, one of the earliest U.S. online video portals, launched on August 9, 2007, and focuses on content from.
The Walt Disney Company and 21st Century Fox. Hulu expanded its service to include a full-featured U.S. service on April 15, 2009, and offers the same premium TV content, local broadcast and regional cable content in addition to content from their online partners. Like Yahoo! Screen and Netflix, Hulu Plus is ad-supported.
