Billboard 200

The Billboard 200 is a record chart ranking the 200 highest-ranking music albums and EPs in the United States, published weekly by Billboard magazine. It is frequently used to convey the popularity of an artist or groups of artists. Often, a recording act will be remembered by its "number ones", those of their albums that outperformed all others during at least one week.

The chart is based mostly on sales (both at retail and digitally) of albums in the United States. The weekly sales period was originally Monday to Sunday when Nielsen started tracking sales in 1991, but since July 2015, tracking week begins on Friday (to coincide with the Global Release Date of the music industry) and ends on Thursday. A new chart is published the following Tuesday with an issue post-dated to the Saturday of the following week. The chart's streaming schedule is also tracked from Friday to Thursday.

New product is released to the American market on Fridays. Digital downloads of albums are also included in Billboard 200 tabulation. Albums that are not licensed for retail sale in the United States (yet purchased in the U.S. as imports) are not eligible to chart. A long-standing policy which made titles that are sold exclusively by specific retail outlets (such as Walmart and Starbucks) ineligible for charting, was reversed on November 7, 2007, and took effect in the issue dated November 17.

The Billboard

The Billboard (77°4′S 145°40′W / 77.067°S 145.667°W / -77.067; -145.667Coordinates: 77°4′S 145°40′W / 77.067°S 145.667°W / -77.067; -145.667) is a massive granite monolith in the Sarnoff Mountains of the Ford Ranges of Marie Byrd Land, West Antarctica, standing just west of Mount Rea between Arthur Glacier and Boyd Glacier. It was discovered in November 1934 by a Second Byrd Antarctic Expedition (1933–35) sledge party under Paul Siple, and is so named because of its form and appearance with vertical faces rising above the continental ice.

The summit was first visited by helicopter in January 1993 during expedition GANOVEX VII. In 1998-99 a geological party from Colorado College reached the summit by climbing a west route.

Geology

It is topped by an erosion surface that reaches an elevation of 793 metres (2,602 ft), which is about 700 m above the outlet glacier below. The surface lacks glacial erosion features such as striae and whaleback forms; however erratics found on the surface provide evidence of overriding by cold-based glacier ice. Features characteristic of prolonged surface weathering in a sub aerial environment are sheeting and weathering pits.

Record chart

A record chart is a ranking of recorded music according to popularity during a given period of time. Examples of music charts are the Hit parade, the Billboard Hot 100 or Top 40.

Many different criteria are used in different charts, including sales of records, cassettes and compact discs, the amount of radio airplay, and since the introduction of digital technology, the number of downloads and the amount of streaming activity.

Some charts are specific to a particular musical genre and most to a particular geographical location (although download charts are not easily pinned down in this way). The most common period of time covered by a chart is one week with the chart being printed or broadcast at the end of this time. Summary charts for years and decades are then calculated from their component weekly charts. Component charts have become an increasingly important way to measure the commercial success of individual songs.

Billboard

A billboard (also called a hoarding in the UK and many other parts of the world) is a large outdoor advertising structure (a billing board), typically found in high-traffic areas such as alongside busy roads. Billboards present large advertisements to passing pedestrians and drivers. Typically showing large, ostensibly witty slogans, and distinctive visuals, billboards are highly visible in the top designated market areas.

The largest standard-size billboards, known as Bulletins, are located primarily on major highways, expressways or principal arterials, and command high-density consumer exposure (mostly to vehicular traffic). Bulletins afford greatest visibility due not only to their size, but because they allow creative "customizing" through extensions and embellishments.

Posters are the other common form of billboard advertising, located mostly along primary and secondary arterial roads. Posters are a smaller format than bulletins and are viewed principally by residents and commuter traffic, with some pedestrian exposure.

200

Year 200 (CC) was a leap year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Severus and Victorinus (or, less frequently, year 953 Ab urbe condita). The denomination 200 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
