From A for AGF Videoforschung to Z for zapping, the most important technical terms in video research are explained here.
The gain and loss analysis examines viewer movements within a broadcaster and a comparison broadcaster during the course of the day. The viewer gains and losses of broadcasters are determined across several programmes or intervals of time.
Unlike special-interest channels, general-interest channels offer a wide range of content in the categories of information, education, advice and entertainment. They are oriented to all television viewers and not individual target groups.
A genre is a category of TV programmes. Comedies, westerns, crime dramas, cartoon series and sitcoms are examples of genres.
GfK Telecontrol is a specialized manufacturer and service provider that operates in the field of television viewer and radio listener measurement. The company is a subsidiary of GfK SE.
GGmedia is a full-service provider in the field of media consulting and research. The company markets television data to production companies in Germany and abroad on behalf of AGF.
GPRS is an acronym that stands for General Packet Radio Service. It refers to a packet-oriented service for the transmission of data in GSM networks. GPRS assures faster data transmission by first converting the data volume into smaller data packets, which are then combined again by the receiving devices.
Gross reach refers to the sum of all persons contacted with a programme or during a certain time interval. Unlike the case of net coverage, overlapping persons are disregarded. In the evaluation software of AGF, gross reach is equivalent to contact total.
The gross reach in percent corresponds to the Gross Raiting Point.
GRP is an acronym that stands for Gross Rating Point. It is calculated as the quotient of the sum of contacts with the included commercial breaks of a campaign divided by the potential in the target group, multiplied by 100. (Alternatively: Average contacts multiplied by the potential market share.) GRP is also referred to as advertising pressure.
A GRP of 120, for example, can mean that 10% of the target group was reached 12 times or 40% of the target group three times. Internal and external overlaps are not taken into account when calculating the GRP.
The CpG indicates the costs per GRP, meaning the costs incurred for a chance of contacting one percent of the target group.
GSM is an acronym that stands for Global System for Mobile Communications. It refers to a transmission technology that is used for telephony and SMS messages. Data transmission via GSM is the most widespread standard for 2G mobile networks.
GWA is an acronym that stands for Gesamtverband der Werbeagenturen (“Federation of Advertising Agencies”). The GWA represents the interests of advertising and media agencies vis-à-vis the media. As members of the governing bodies of AGF, its delegates participate in the monitoring and further development of television audience research. The Organisation der Media-Agenturen im GWA (“Organization of Media Agencies within the GWA”) or OMG, which was formed at the start of 2000, represents media agencies in Germany, as well as the media side of agencies in cooperation with the GWA. The agencies are also represented in AGF via the OMG.
