'', a technology streaming continuous music to commercial customers without the use of radio. The Telephone Music Service, a live jukebox service, began in 1929 and continued until 1997. The clientele eventually included 120 bars and restaurants in the Pittsburgh area. A tavern customer would deposit money in the jukebox, use a telephone on top of the jukebox, and ask the operator to play a song. The operator would find the record in the studio library of more than 100,000 records, put it on a turntable, and the music would be piped over the telephone line to play in the tavern. The music media began as 78s, 33s and 45s, played on the six turntables they monitored. CDs and tapes were incorporated in later years. The business had a succession of owners, notably Bill Purse, his daughter Helen Reutzel, and finally, Dotti White. The revenue stream of each quarter was split 60% to the music service and 40% to the tavern owner. This business model eventually became unsustainable due to city permits and the cost of setting up these telephone lines.


History


Early development

Attempts to display media on computers date back to the earliest days of computing in the mid-20th century. However, little progress was made for several decades, primarily due to the high cost and limited capabilities of computer hardware. From the late 1980s through the 1990s, consumer-grade personal computers became powerful enough to display various media. The primary technical issues related to streaming were having enough CPU and

. Competition among online platforms has forced them to find ways to differentiate themselves. One key way they have done this is by offering exclusive content, often self-produced and created specifically for a market. This approach to streaming competition, can have disadvantages for consumers and for the industry as a whole. Once content is made available online, the corresponding piracy searches decrease. Competition or legal availability across multiple platforms effectively deters online piracy and more exclusivity does not necessarily translate into higher average investment in content, as investment decisions are also dependent on the level and type of competition in online markets. This competition was increased during the first two years of the

s emerged to offer listeners a non-technical option for listening to audio streams. These audio streaming services became increasingly popular; streaming music reached 118.1 billion streams in 2013. In general, multimedia content is data intensive, so media storage and transmission costs are still significant. Media is generally compressed for transport and storage. Increasing consumer demand for streaming of high-definition (HD) content has led the industry to develop technologies such as WirelessHD and G.hn, which are optimized for streaming HD content. Many developers have introduced HD streaming apps that work on smaller devices such as tablets and smartphones for everyday purposes. A media stream can be streamed either ''live'' or ''on demand''. Live streams are generally provided by a means called ''true streaming''. True streaming sends the information straight to the computer or device without saving to a local file.

. In an interview from 2009, Shawn Fanning explained that Napster "was something that came to me as a result of seeing a sort of an unmet need and the passion people had for being able to find all this music, particularly a lot of the obscure stuff which wouldn't be something you go to a record store and purchase, so it felt like a problem worth solving." Not only did this development disrupt the music industry by making songs that previously required payment to acquire freely accessible to any Napster user, but it also demonstrated the power of P2P networks in turning any digital file into a public, shareable good. For the brief period of time that Napster existed, mp3 files fundamentally changed as a type of good. Songs were no longer financially excludable – barring access to a computer with internet access – and they were not rival, meaning if one person downloaded a song it did not diminish another user from doing the same. Napster, like most other providers of public goods, faced the
free-rider problem In the social sciences, the free-rider problem is a type of market failure that occurs when those who benefit from resources, public goods (such as public roads or public library), or services of a communal nature do not pay for them or under-p ...
. Every user benefits when an individual uploads an mp3 file, but there is no requirement or mechanism that forces all users to share their music. Thus, Napster users were incentivized to let others upload music without sharing any of their own files. This structure revolutionized the consumer's perception of ownership over digital goods – it made music freely replicable. Napster quickly garnered millions of users, growing faster than any other business in history. At the peak of its existence, Napster boasted about 80 million users globally. The site gained so much traffic that many college campuses had to block access to Napster because it created network congestion from so many students sharing music files. The advent of Napster sparked the creation of numerous other P2P sites including

In addition to this, the Recording Industry Association of America (RIAA) also filed a lawsuit against Napster on the grounds of unauthorized distribution of copyrighted material, which ultimately led Napster to shut down in 2001. In an interview with the ''New York Times'', Gary Stiffelman, who represents Eminem, Aerosmith, and TLC, explained, "I’m not an opponent of artists’ music being included in these services, I'm just an opponent of their revenue not being shared."


The fight for intellectual property rights: ''A&M Records, Inc. v. Napster, Inc.''

The lawsuit '' A&M Records, Inc. v. Napster, Inc.'' fundamentally changed the way consumers interact with music streaming. It was argued on 2 October 2000 and was decided on 12 February 2001. The

for the Ninth Circuit ruled that a P2P file-sharing service could be held liable for contributory and vicarious infringement of copyright, serving as a landmark decision for Intellectual property law. The first issue that the Court addressed was

, which says that otherwise infringing activities are permissible so long as it is for purposes "such as criticism, comment, news reporting, teaching ..scholarship, or research." Judge Beezer, the judge for this case, noted that Napster claimed that its services fit "three specific alleged fair uses: sampling, where users make temporary copies of a work before purchasing; space-shifting, where users access a sound recording through the Napster system that they already own in audio CD format; and permissive distribution of recordings by both new and established artists." Judge Beezer found that Napster did not fit these criteria, instead enabling their users to repeatedly copy music, which would affect the market value of the copyrighted good. The second claim by the plaintiffs was that Napster was actively contributing to
copyright infringement Copyright infringement (at times referred to as piracy) is the use of works protected by copyright without permission for a usage where such permission is required, thereby infringing certain exclusive rights granted to the copyright holder, s ...
since it had knowledge of widespread file sharing on its platform. Since Napster took no action to reduce infringement and financially benefited from repeated use, the court ruled against the P2P site. The court found that "as much as eighty-seven percent of the files available on Napster may be copyrighted and more than seventy percent may be owned or administered by plaintiffs." The injunction ordered against Napster ended the brief period in which music streaming was a public good – non-rival and non-excludable in nature. Other P2P networks had some success at sharing MP3s, though they all met a similar fate in court. The ruling set the precedent that copyrighted digital content cannot be freely replicated and shared unless given consent by the owner, thereby strengthening the property rights of artists and record labels alike.

have shifted music streaming to a club-type good. While some platforms, most notably Spotify, give customers access to a freemium service that enables the use of limited features for exposure to advertisements, most companies operate under a premium subscription model. Under such circumstances, music streaming is financially excludable, requiring that customers pay a monthly fee for access to a music library, but non-rival, since one customer's use does not impair another's. Spotify has over 207 million users in 78 countries, Apple Music has about 60 million, and SoundCloud has 175 million. All platforms provide varying degrees of accessibility. Apple Music and Prime Music only offer their services for paid subscribers, whereas Spotify and SoundCloud offer freemium and premium services. Napster, owned by Rhapsody since 2011, has resurfaced as a music streaming platform offering subscription-based services to over 4.5 million users . The music industry's response to music streaming was initially negative. Along with music piracy, streaming services disrupted the market and contributed to the fall in US revenue from $14.6 billion in 1999 to $6.3 billion in 2009. CDs and single-track downloads were not selling because content was freely available on the Internet. By 2018, however, music streaming revenue exceeded that of traditional revenue streams (e.g. record sales, album sales, downloads). Streaming revenue is now one of the largest driving forces behind the growth in the music industry. In an interview, Jonathan Dworkin, a senior vice president of strategy and business development at Universal, said, "We cannot be afraid of perpetual change, because that dynamism is driving growth."

, Apple TV, Google TV or a Sony TV Blu-ray Disc Player. 5 Mbit/s is recommended for high-definition content and 9 Mbit/s for ultra-high-definition content. Streaming media storage size is calculated from the streaming bandwidth and length of the media using the following formula (for a single user and file): storage size in megabytes is equal to length (in seconds) × bit rate (in bit/s) / (8 × 1024 × 1024). For example, one hour of digital video encoded at 300 kbit/s (this was a typical broadband video in 2005 and it was usually encoded in resolution) will be: (3,600 s × 300,000 bit/s) / (8 × 1024 × 1024) requires around 128  MB of storage. If the file is stored on a server for on-demand streaming and this stream is viewed by 1,000 people at the same time using a Unicast protocol, the requirement is 300 kbit/s × 1,000 = 300,000 kbit/s = 300 Mbit/s of bandwidth. This is equivalent to around 135  GB per hour. Using a

protocol the server sends out only a single stream that is common to all users. Therefore, such a stream would only use 300 kbit/s of serving bandwidth. See below for more information on these protocols. The calculation for live streaming is similar. Assuming that the speed at the encoder is 500 kbit/s and if the show lasts for 3 hours with 3,000 viewers, then the calculation is number of MBs transferred = encoder speed (in bit/s) × number of seconds × number of viewers / (8 × 1024 × 1024). The results of this calculation are as follows: number of MBs transferred = 500 x 1024 (bit/s) × 3 × 3,600 ( = 3 hours) × 3,000 (number of viewers) / (8 × 1024 × 1024) = 1,977,539 MB. In 2018 video was more than 60% of data traffic worldwide and accounted for 80% of growth in data usage.

(TCP), guarantee correct delivery of each bit in the media stream. However, they accomplish this with a system of timeouts and retries, which makes them more complex to implement. It also means that when there is data loss on the network, the media stream stalls while the protocol handlers detect the loss and retransmit the missing data. Clients can minimize this effect by buffering data for display. While delay due to buffering is acceptable in video on demand scenarios, users of interactive applications such as video conferencing will experience a loss of fidelity if the delay caused by buffering exceeds 200 ms.

Challenges


Copyright issues

The availability of large bandwidth internet enabled the audiovisual streaming services to attract large number of users around the world.  For OTT platforms, original content represents a critical variable in order to capture more subscribers. This generated a number of effects related to the copyright over the audiovisual content and its international exploitation through streaming such as contractual practices, international exploitation of rights, widespread use of standards and metadata in digital files. The WIPO has indicated the several basic copyright issues arising for those pursuing to work in the film and music industry in the era of streaming. Streaming copyrighted content can involve making infringing copies of the works in question. The recording and distribution of streamed content is also an issue for many companies that rely on revenue based on views or attendance.
