Deezer

Deezer (stylized as deezer) is a French online music streaming service. It allows users to listen to music content from record labels, including Universal Music Group, Sony Music and Warner Music Group (owned by Deezer's parent company Access Industries) as well as podcasts on various devices online or offline. 
Created in Paris, France, Deezer currently has 73 million licensed tracks in its library, with over 30,000 radio channels, 14 million monthly active users, and 7 million paid subscribers as of January 2019. The service is available for Web, Android, iOS, Windows Mobile, BlackBerry OS, Windows, and MacOS.
History.
In 2006, Daniel Marhely developed the first version of Deezer, called Blogmusik, in Paris. His idea was to give unlimited access to music lovers through streaming technology.
The site in its original incarnation was charged with copyright infringement by French agency SACEM, and after being shut down in April 2007, it was relaunched as Deezer in August 2007, having reached an agreement with SACEM to pay copyright holders with revenue from advertising on the site and by giving users the ability to download songs streamed on Deezer from iTunes, with Deezer receiving a commission from each purchase.
Launch.
At the time of its launch in 2007, Deezer had not yet negotiated agreements with major music labels and therefore offered a limited catalogue. It took more than two years for agreements to be signed with the four largest labels, as well as various smaller ones, but by 2011 the company had rights to about eight million songs. During August 2007, its first month of operations, Deezer saw about 773,000 visitors to its site, with traffic increasing rapidly in the next several years—2.75 million people used the service in May 2008, and there were seven million users by December 2009.
Despite the high traffic, Deezer almost immediately ran into financial problems—during the first half of 2008, the company saw revenue of just 875,000 euros, not enough to pay its licensing fees. In July 2008, the company began running ads itself through advertising agency Deezer Media; in October, Deezer secured $8.4 million in funding from AGF Private Equity and CM-CIC Capital Prive, bringing total investment in the company to $15.8 million. The company introduced mandatory registration in February 2009 to gather more precise data on users, in order to run more targeted ads, and in November 2009 began running audio ads between songs.
On 5 November 2009, Deezer launched a new three-tier service model. While continuing basic free web streaming, the company also introduced two subscription services—users paying €4.99 monthly received higher-quality music without ads, and users paying €9.99 monthly gained access to downloadable applications for computers, as well as Android, BlackBerry, and iOS mobile devices.
In January 2010, the company's CEO and co-founder, Jonathan Benassaya, was replaced as CEO by Axel Dauchez, after fewer than 15,000 of Deezer's 12 million users signed up for its subscription services. In August 2010, mobile operator Orange partnered with Deezer in a deal to include free access to Deezer Premium, the highest tier of Deezer's streaming packages, with some of Orange's telecommunications contracts in France. Almost immediately after the partnership began, the rate of users signing up for Deezer's premium services went from 6,000 a month to 100,000; by January 2011, 500,000 people were subscribing to the service, with the million-subscriber mark reached in the middle of 2011, half a year ahead of schedule. The two companies expanded their partnership in September 2011 to include Orange contract customers in the United Kingdom. Also in September, Deezer added Facebook integration to its service, allowing users to send music to one another via that social media service.
Expansion to more countries.
Deezer was launched in France in 2007, where it was the market leader as of 2017. On 7 December 2011, Deezer, at the time available only in Belgium, France and the United Kingdom, announced plans to expand worldwide during the rest of 2011 and continuing into 2012. According to the company, it planned to make its services available to the whole of Europe by the end of the year, to the Americas (excluding the United States) by the end of January 2012, to Africa and Southeast Asia by the end of February, and the rest of the world (excluding Japan) by the end of June.
It took until 15 March 2012 for service to be available across the whole of Europe, while service launched in Australia, Canada, and New Zealand on 25 April. On 8 June, Deezer announced availability in 35 Latin American countries, though not in Brazil, Cuba, or Venezuela. On 15 August, Deezer announced it would be available in Indonesia, Malaysia, Pakistan, the Philippines, Singapore, and Thailand within several weeks.
On 8 October 2012, Deezer announced that it had received $130 million in funding from Access Industries, to be used for further international expansion. Two days later, the company announced that it had expanded into 76 new markets, bringing its worldwide total to 160 countries. On 21 December, Deezer announced a new service level offering two hours of free, ad-supported music streaming a month, available to users worldwide, the company's first free music streaming service outside France. CEO Dauchez said that Deezer was also looking for a partner to introduce service in the United States, who was "able to provide us with a significant volume of subscribers" to help offset what he called the "unbelievably high" costs of entering the US market.
As of December 2012, Deezer had about two million users paying for subscriptions, out of a monthly active user base of about seven million, with 20 million songs in its library. By 2016, according to CEO Dauchez, the company aimed to have five percent of the global music market.
In January 2013, Deezer announced its expansion into 22 new countries across Africa, Asia, Brazil, the Middle East, and the United States, bringing its total to 182. However, the United States launch has been restricted to a limited number of device promotions. In July 2016, Deezer added the U.S. to the supported country list. As of February 2018, Deezer listed on its website 189 countries where the service was available.
After expansion.
Following this expansion, Deezer announced in 2013 partnerships with LG Electronics, Samsung Electronics, and Toshiba that saw Deezer apps made available on smart TV platforms, along with a new brand identity developed in association with the illustrator mcbess.

In June 2014, Deezer announced a new partnership with Samsung giving Samsung Galaxy S5 users in Europe a free, six months Deezer Premium+ subscription. Samsung and Deezer extended their partnership by offering a six-month, free of charge subscription to Deezer Premium+ for Samsung's Multiroom Wireless Audio Products, including its M5 and M7 line of Multiroom wireless audio speakers.
