Advertising Targeting (Internet) The web allows adverts to be targeted primarily in three ways. 1 By web publication - which allows advertisers to target campaigns based on the simple level of the known demographics of a publication. 2 The choice of content within a web publication. This is particularly important in large online publications such as Electronic Telegraph, which may contain pockets of content targeted at certain groups - for example medical news pages being read by doctors and consumers interested in health issues. 3 Dynamically targeted adverts which deliver different adverts to different groups of readers while they are reading the same page. New software which is being adopted in 1997 by some of the main UK new media publishers is opening up the direct marketing potential of the web. There are two types of dynamic targeting. The first, and simplest, allows adverts to be targeted from information which is carried to the website by the users browser. Typically this will include the type of browser and computer, a generalised statement of what country they are reading from (unfortunately this is based on domain names and often fails) and information about which websites they have visited. The second method is only open to sites like the Telegraphs Electronic Telegraph which have a registered base of users for which they know certain characteristics. In theory an advert could be targeted based on any of the data captured in the questionnaire such as age, gender, occupation.

Lastly the rules will often additionally specify the distribution of commercial minutage by time of day, the frequency and positioning of commercial breaks within and between programmes, the duration of commercial breaks and other requirements, such as the obligation on some TV channels to sell all their airtime in order to limit TV channel manipulation of advertising demand and consequent airtime prices.

CRR is intended to protect the advertising market: a) by guaranteeing that advertisers and media buyers are no worse off following the merger of Carlton and Granada; and b)by putting in place an automatic ratchet which reduces the amount advertisers have to commit if ITVs audience shrinks. The CRR sets out a number of rights that advertisers and media buyers have when buying advertising time from Carlton/Granada, and in particular, gives advertisers and media buyers the right to renew their contracts on a rolling annual basis, adjusted for changes in ITVs audiences, with no reduction in the discounts they receive. Until the remedy is no longer necessary, the share of revenue committed by advertisers/media buyers on television advertising to Carlton/Granada need not increase above 2003 levels.

Normally the dot on the film can be reproduced at almost exactly the same size on the metal printing plate, but in the printed version the size may have increased. This is a result of various factors, including the blanket, the machine, the inks and paper being used. The reproduction house must therefore allow dot gain in the reproduction and proofing process. This is done by, in effect, purposely making the dot on the film smaller than it 'should' be as to allow for the gain that will take place at the printing stage.

Dynamic advertising targeting Dynamically targeted adverts which deliver different adverts to different groups of readers while they are reading the same page. New software which is being adopted in 1997 by some of the main UK new media publishers is opening up the direct marketing potential of the web. There are two types of dynamic targeting. The first, and simplest, allows adverts to be targeted from information which is carried to the website by the users browser. Typically this will include the type of browser and computer, a generalised statement of what country they are reading from (unfortunately this is based on domain names and often fails) and information about which websites they have visited. The second method is only open to sites like the Telegraphs Electronic Telegraph which have a registered base of users for which they know certain characteristics. In theory an advert could be targeted based on any of the data captured in the questionnaire such as age, gender, occupation.

Effective Sample Size The sample size after reductions due to weighting and design factors have been taken into account.
Effective/equivalent sample size Also termed equivalent, effective sample size denotes the estimated size of the sample based on sample error and after removing the effects of weights and dependencies within the sample caused by clustering (i.e. individuals within the same sample population living in the same household). In practice, measures of effective sample size are usually calculated by examining the effects of panel weights alone. For single audience measures, the effective sample will always be lower than the actual sample on the basis that, the greater the variability of panel weights within the selected sample/sub-sample, the lower the effective sample size.

The actual quality of HD broadcast will depend on several factors, such as how well operators follow the technical specifications. The superior quality of HD over SD signal quality also becomes steadily more noticeable with larger screen sizes.

P2P (Peer-to-peer) Peer-to-peer/P2P networks are the alternative to central server networks. Instead of all members feeding of a central server that responds to user requests, P2P networks use the connectivity between participants in the network to handle traffic, whereby requests are handled across the total pool of participants, each of whom contributes to the total computing power, storage space and bandwidth of the network. An important advantage is that the capacity of P2P networks increases as they add members. This is in sharp contrast to client-server networks, where additional customers will cause lower transfer speeds. For content distributors, the appeal of P2P networking is that it reduces central overheads. (see also File sharing)

Typically the feed is taken from one master station. The stations that form part of a package are not restricted to a specific sales point.

Peoplemeter measurement General methodology for collecting TAM data by means of a household panel sample equipped with a dual metering system that registers (a) TV set status (i.e. which channel is being tuned to) and (b) viewer presence. Peoplemeter TAM research is currently restricted to measuring in-home audiences with meters attached to each TV set. Introduced commercially during the mid eighties, peoplemeter measurement now predominates over all other TAM methodologies throughout the world. Its key advantages for the advertising community are that it offers highly detailed (minute by minute or even second by second) continuous audience measurement for 24 hours a day and 365 days a year, and is impartial, being free from bias compared with the interview and diary-based recall methodologies.

In the case of TV set status, the main purpose of persistence thresholds is to reduce data loads significantly by cutting out very short viewing statements (e.g. bouts of zapping). Until a permanent change of channel is recorded, the meter will continue to record the most recent channel/set use as if no change(s) had taken place. This entails the assumption that consequent errors of attribution are balanced across channels.
