Windows Live Messenger

Windows Live Messenger (formerly MSN Messenger) is a discontinued instant messaging client developed by Microsoft for Windows, Xbox 360, BlackBerry OS, iOS, Java ME, S60 on Symbian OS 9.x, and Zune HD. It connected to the Microsoft Messenger service while also having compatibility with Yahoo! Messenger and Facebook Messenger. The client was first released as MSN Messenger on July 22, 1999, and was marketed under the MSN branding until 2005 when it was rebranded under Windows Live and has since been officially known by its present name, although its previous name was still used colloquially by most of its users. In June 2009, Microsoft reported the service attracted over 330 million active users each month, placing Messenger among the most widely used instant messaging clients in the world.

Following the acquisition of Skype Technologies in May 2011, Microsoft added interoperability between Skype and Microsoft accounts, allowing Skype (which had features unique to its platform and a wider user base) to communicate with Messenger contacts. In 2013, Windows Live Messenger was discontinued and Microsoft began ceasing service to existing clients. The service in China remained active for another 18 months, and ceased operations on October 31, 2014.

Electronic dance music

Electronic dance music (also known as EDM, dance music,club music, or simply dance) is a broad range of percussive electronic music genres produced largely for nightclubs, raves, and festivals. Produced for playback by disc jockeys (DJs), EDM is generally used in the context of a live mix, where a DJ creates a seamless selection of tracks by segueing from one recording to the next.

By the early 2010s the term "electronic dance music" and the initialism "EDM" was being pushed by the U.S. music industry and music press in what was largely an effort to re-brand U.S. rave culture. In the UK, "dance music" or "dance" are more common terms for EDM. In this context, EDM does not refer to a specific genre, but serves as an umbrella term for several commercially-popular genres, including techno, house, trance, hardstyle, drum and bass, dubstep, trap, Jersey club and their respective subgenres.

History

Early examples of electronic dance music include the disco music of Giorgio Moroder and the electronic music of Kraftwerk and Yellow Magic Orchestra in the late 1970s.

Dance music

Dance music is music composed specifically to facilitate or accompany dancing. It can be either a whole musical piece or part of a larger musical arrangement. In terms of performance, the major categories are live dance music and recorded dance music. While there exist attestations of the combination of dance and music in ancient times (for example Ancient Greek vases sometimes show dancers accompanied by musicians), the earliest Western dance music that we can still reproduce with a degree of certainty are the surviving medieval dances. In the Baroque period, the major dance styles were noble court dances (see Baroque dance). In the classical music era, the minuet was frequently used as a third movement, although in this context it would not accompany any dancing. The waltz also arose later in the classical era. Both remained part of the romantic music period, which also saw the rise of various other nationalistic dance forms like the barcarolle, mazurka and polonaise.

Modern popular dance music initially emerged from late 19th century's Western ballroom and social dance music. During the early 20th century, ballroom dancing gained popularity among the working class who attended public dance halls. Dance music became enormously popular during the 1920s. In the 1930s, called the Swing era, Swing music was the popular dance music. In the 1950s, Rock and roll became the popular dance music. The late 1960s saw the rise of soul and R&B music. The rise of disco in the early 1970s led to dance music becoming popular with the public. By the late 1970s, a new form of dance music was developing. This music, made using electronics, is a style of popular music commonly played in dance music nightclubs, radio stations, shows and raves. Many subgenres of electronic dance music have evolved.
