Nursery rhyme

A nursery rhyme is a traditional poem or song for young children in Britain and many other countries, but usage only dates from the late 18th /early 19th century. In North America the term Mother Goose Rhymes, introduced in the mid-18th century, is still often used.

History

Lullabies

The oldest children's songs of which we have records are lullabies, intended to help a child sleep. Lullabies can be found in every human culture. The English term lullaby is thought to come from "lu, lu" or "la la" sound made by mothers or nurses to calm children, and "by by" or "bye bye", either another lulling sound, or a term for good night. Until the modern era lullabies were usually only recorded incidentally in written sources. The Roman nurses' lullaby, "Lalla, Lalla, Lalla, aut dormi, aut lacta", is recorded in a scholium on Persius and may be the oldest to survive.

Many medieval English verses associated with the birth of Jesus take the form of a lullaby, including "Lullay, my liking, my dere son, my sweting" and may be versions of contemporary lullabies. However, most of those used today date from the 17th century. For example, a well known lullaby such as "Rock-a-bye, baby on a tree top", cannot be found in records until the late-18th century when it was printed by John Newbery (c. 1765).

Music video

A music video or song video is a short film integrating a song and imagery, produced for promotional or artistic purposes. Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie in marketing campaigns that allow them to become more than just a song. Tie ins and merchandising could be used in toys are marketing campaigns for food and other products. Although the origins of music videos date back to musical short films that first appeared in the 1920s, they came into prominence in the 1980s when MTV based their format around the medium. Prior to the 1980s, these works were described by various terms including "illustrated song", "filmed insert", "promotional (promo) film", "promotional clip", "promotional video", "song video", "song clip" or "film clip". Since the creation and increased popularity of YouTube, mainstream artists now promote new music videos by releasing trailers of short promos on the site for their upcoming song and music video. Consequentially, YouTube has been converted into a social media platform for celebrities and artists to market themselves to their fans and audiences.

Pokémon GO

Pokémon GO is an upcoming augmented reality game for mobile phones developed by Niantic, scheduled to be released in 2016 for iOS and Android devices. The game will be released alongside the Pokémon Go Plus, a small wearable device developed by Nintendo, which uses a Bluetooth connection to notify users when a Pokémon is nearby with a LED and a light rumble. The game will allow players to capture, battle, train and trade virtual Pokémon who appear throughout the real world. The game will be free-to-play, although it will support in-app purchases.

The idea for the game was conceived in 2013 by Satoru Iwata of Nintendo and Tsunekazu Ishihara of The Pokémon Company. In 2015, Ishihara dedicated his speech at the game's announcement on September 10 to Iwata, who died two months earlier. Ishihara and his wife had played Ingress. Different Pokémon will live in different areas of the world - for example, water type Pokémon will live near water. There will be events held where players can trade Pokémon to build up their collection. A wristband device called the "Pokémon Go Plus" will ship with the game, to allow a more "heads-up" gaming experience than Ingress, where the player can be alerted to a nearby Pokémon by the Go Plus vibrating, press the button in a coded sequence to capture it and check the app later to find out what they've captured. The decision to create the Go Plus rather than create a smart watch app was to increase uptake among players for whom a smart watch is prohibitively expensive.
