BBC Breakfast

BBC Breakfast is a national British morning television news programme simulcast on BBC One and BBC News. It is presented live from MediaCityUK and contains a mixture of news, sport, weather, business and feature items. The programme is broadcast seven days a week, every week of the year, including weekends and public holidays.

Adam Bullimore is the editor. He had been the deputy editor for five years. Alison Ford, previously the UK Editor for BBC Newsgathering, was the editor of the programme until her death in July 2013. Her appointment followed the departure of David Kermode to 5 News.

History

Breakfast Time was the first BBC breakfast programme, with Ron Neil as producer. It was conceived in response to the plans of the commercial television company TV-am to introduce a breakfast television show. Breakfast Time's first broadcast was on 17 January 1983, featuring multiple presenters: Frank Bough, Selina Scott, Nick Ross and Russell Grant. The atmosphere of the set was intended to encourage a relaxed informality; a set that mimicked a living-room rather than a studio, with red leather sofas, and Bough and Ross wearing jumpers and open-necked shirts. This allowed for an unconventional mix of authoritative and highbrow news and informative and entertainment features that made the show dominate the new genre and trounce the anticipated threat by the star-name commercial TV rival. So, a senior government minister might be subjected to intense questioning while sitting on the red sofa, to be then included in the presentation of a food cooking demonstration. Breakfast Time lasted 150 minutes, initially being transmitted between 6.30 am and 9 am—moving to a 6.50 am to 9.20 am slot on 18 February 1985.

Shot grouping

In shooting, a shot grouping, or simply grouping, is the placement of multiple shots on a target, the shots taken in one shooting session. The closeness of the grouping, the nearness of all the shots to each other, is a measure of the accuracy of a weapon, and a measure of the shooter's consistency and skill.

Uses of the term

For firearms that shoot one round at a time, a shot grouping can be used to measure the accuracy of the system comprised out of weapon as well as the precision and uniformity of the ammunition by fixing the weapon into position on a test mount, and aiming it at a target. Multiple shots using rounds from same type and batch are fired to observe how the weapon groups the shots. If a person holds the weapon and shoots it, the grouping measures the combination of the person's skill and the weapon's accuracy.

In shotgun shooting, the grouping is also called the pattern. The pattern is the spread of shot from a single shotgun shell, measured as the smallest circle containing all the shots on the target. The barrel of a shotgun is designed to deliver a wide or narrow grouping, depending on the expected use. Shooting at close range indicates a cylinder bore barrel to deliver a wide grouping, while for hunting at longer distances such as 50 yards or meters, a choke is recommended for a tighter grouping.

Stratigraphic unit

A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it.

Units must be mappable and distinct from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%".

Lithostratigraphic units

Sequences of sedimentary and volcanic rocks are subdivided on the basis of their lithology. Going from smaller to larger in scale, the main units recognised are Bed, Member, Formation, Group and Supergroup.

Bed

A bed is a lithologically distinct layer within a member or formation and is the smallest recognisable stratigraphic unit. These are not normally named, but may be in the case of a marker horizon.

Member

A member is a named lithologically distinct part of a formation. Not all formations are subdivided in this way and even where they are recognized, they may only form part of the formation.
