The video plays right away. It does not wait to finish. This happens because the video is sent in small pieces. These pieces move from a big computer to yours. 
This is called streaming. You can stream music, too. Some people use it to watch live shows. You can even stream music to a car.
Streaming is a very popular way to see things. It is fun to watch!
Streaming media is a way to watch or listen to things online. 
Streaming media is a way to send sounds and pictures through a network.
How does this stream of data actually work? The media travels from a remote server over the Internet. It can also move between devices on a local area network. For example, you might use a home server at home. You can also use Bluetooth to send audio to speakers. Bluetooth uses radio waves instead of the usual Internet paths. Streaming is not just for video or audio files. It can even include streaming text like live closed captioning. This way of sending data helps us see things instantly. It keeps the media moving without long waits.
People have tried to send media over lines for a long time. In 1881, a system called Théâtrophone let people hear opera over telephone lines. This service lasted until 1932. Later, the Telharmonium was patented in 1897. In the 1920s, George Owen Squier made a system for electrical lines. This technology became known as Muzak. Another service called the Telephone Music Service began in 1929. It lasted until 1997 and served 120 bars in Pittsburgh. Customers used a telephone to ask an operator for a song. The operator played records from a library of 100,000 items. This music was then piped over the telephone line.
Modern streaming grew quickly in the 1990s and 2000s. Companies like RealNetworks and Microsoft helped make it popular. In 1993, a band called Severe Tire Damage played a live gig on the Internet. They used about half of the total Internet bandwidth for it. In 1994, a school music festival in New Zealand was webcast. It had 16 viewers in 12 different countries. RealNetworks also streamed a baseball game in 1995. That game was between the New York Yankees and the Seattle Mariners. In 1996, Marc Scarpa produced a large live broadcast for a concert. These early steps helped build the tools we use today.
Streaming is now a huge part of our daily lives. We use it to listen to music on wireless speakers. Many people use subscription services to find their favorite songs. 
Streaming media is a method of delivering multimedia through a network for immediate playback. This technology allows users to watch videos or listen to music using a media player. Unlike file downloading, where a user must obtain an entire file before using it, streaming happens in real-time or near real-time. 
The mechanism of streaming relies on the transfer of data in a stream of packets. These packets move from a server to a client device. The client then renders the media as it arrives. This is a continuous flow of information. If the data does not arrive fast enough, it can cause a buffer underrun. This is a problem where the playback stops because the device has no data to show. To prevent this, devices often download parts of the media in the background.
There are different types of streaming delivery methods. Live streaming is the real-time delivery of content during its production. This is very similar to how live television broadcasts content through specific channels. 
History shows that the desire to transmit media is very old. In 1881, the Théâtrophone allowed subscribers to listen to opera via telephone lines. This service operated until 1932. In 1897, the Telharmonium was patented. Later, in the 1920s, George Owen Squier patented a system for distributing signals over electrical lines. This technology became the basis for Muzak. Another interesting example was the Telephone Music Service, which ran from 1929 to 1997. It served 120 bars and restaurants in Pittsburgh. Customers used a telephone to request songs from a library of 100,000 records. An operator would play the record on a turntable and pipe the music through the phone line.
Modern digital streaming faced many technical hurdles. Early computers lacked the CPU and bus bandwidth to support high data rates. In the mid-1990s, networks were still quite limited. Practical streaming required advances in data compression. Uncompressed audio requires 1.4Mbit/s for CD quality. Raw SD video requires 168Mbit/s, while FHD video needs over 1000Mbit/s. Without compression, these requirements were too high for most networks. In the 1990s, companies like RealNetworks and Microsoft helped popularize online streaming. These companies helped move the technology from specialized uses to the general public.
Early internet milestones helped prove the potential of live streaming. In 1993, the band Severe Tire Damage performed a live gig at Xerox PARC. They used roughly half of the total internet bandwidth at the time. The video was pixelated and the audio quality was like a bad telephone connection. In 1994, a school music festival in New Zealand was webcast to 16 viewers in 12 countries. By 1995, RealNetworks pioneered the streaming of a baseball game between the Yankees and the Mariners. These early experiments showed that the internet could host massive, real-time events.
Today, streaming is a dominant force in how we consume media. It has changed the way we interact with music and video. Instead of buying physical copies, many people use subscription services.
