Patent Application
20210224854
The present disclosure relates to a spot planning evaluation system, a spot planning evaluation apparatus and a program.
In television broadcast, CMs (commercial messages) are broadcast as advertisements. The CMs are roughly classified into time CMs and spot CMs. The time CMs are CMs broadcast in slots that are bought and sold being integrated with a program and may be called program commercial messages, program CMs or sponsor CMs.
The spot CMs correspond to CMs broadcast in CM time slots determined by television stations. The spot CMs are classified into station breaks (SB) broadcast between programs, participations (PT) (or participating CMs) inserted in a program but are not attached with a sponsor display, and the like.
Existing spot CM planning (which may be called selection of advertisement slots, plan making, buying, quotation, spot planning and the like) is performed based on an advertisement placement pattern determined in advance (for example Patent Literature 1).
As for the existing spot CM planning (which may be called spot planning), however, since there is a restriction to follow an existing placement pattern, there is a problem that more effective planning for a particular target audience cannot be provided.
Therefore, one of objects of the present disclosure is to provide a spot planning evaluation system, a spot planning evaluation apparatus and a program capable of placing an efficient advertisement for a particular target.
A spot planning evaluation system according to one aspect of the present disclosure includes: an acquisition unit configured to acquire information for identifying effective areas configured with advertisement slots with particular-target content rates equal to or larger than a given threshold; and a control unit configured to perform, in order that a sum total of total audience ratings (acquired gross rating point (GRP) rates) expected to be acquired by the advertisement slots of the effective areas with respect to all advertisement slots during a given period becomes a given value, adjustment of acquired GRP rates of all the advertisement slots during a given period.
According to one aspect of the present disclosure, it is possible to place an efficient advertisement for a particular target.
Existing spot CM planning (which may be called buying, quotation or the like) is performed based on a household audience rating in the case of assuming an advertisement placement pattern determined in advance. As the advertisement placement pattern, there are, for example, an inverted L type, an all-day type, an inverted E-shaped type, an inverted C-shaped type, an inverted F type, a midnight type, an all-daytime type and the like. Note that, in the present disclosure, the advertisement placement pattern may be replaced with a placement pattern, a development pattern, an advertisement pattern, a sales pattern or the like.
Generally, spot CM planning is performed in the unit of total audience rating (gross rating point (GRP)). Cost per GRP is called cost per point. Generally, the cost per point differs for each placement pattern. A spot CM fee in the case of selecting a certain placement pattern may be calculated based on GRP x cost per point.
As for the existing spot CM planning (which may be called spot planning), however, since there is a restriction to follow an existing placement pattern, there is a problem that more effective planning cannot be provided for a particular target.
Therefore, the present inventors got an idea of a mechanism capable of realizing evaluation for performing buying of advertisement slots appropriate for a target, utilizing various data.
An embodiment of the present disclosure will be described below in detail with reference to accompanying drawings. In the description below, the same units are given the same reference numerals. Since the same units have the same name and the same function, detailed description will not be repeated.
The spot planning evaluation apparatus 10 is an apparatus to try exchange of advertisement slots among a plurality of advertisement campaigns and provide information about an exchange result. Hereinafter, the spot planning evaluation apparatus 10 is also called simply the evaluation apparatus 10 below.
The evaluation apparatus 10 may be a mobile terminal (a mobile communication terminal) such as a mobile phone, a smartphone and a tablet type terminal or may be a fixed communication terminal such as a personal computer (PC) and a server. In other words, the evaluation apparatus 10 in the present disclosure can be replaced with a communication device.
The evaluation apparatus 10 may communicate with a network (the Internet and the like) wiredly and/or wirelessly (via, for example, LTE (Long Term Evolution), NR (New Radio), Wi-Fi (registered trademark) and the like).
The broadcast distribution apparatus 20 is an apparatus to distribute broadcast to TVs (televisions). Here, the televisions (television receivers) may be apparatuses having a function of receiving at least one of terrestrial broadcast, broadcasting by BS (Broadcasting Satellite)/CS (Communications Satellite), Internet broadcasting (Internet television) and the like. For example, the televisions may be multi-function televisions, smart TVs, IP (Internet Protocol) TVs, set top boxes or the like.
Note that broadcasting means transmission of telecommunication intended to be directly received by the public, and may include radio broadcasting and Internet broadcasting.
The audience rating management apparatus 30 is an apparatus to perform aggregation for an actual audience rating of a program broadcast on televisions. The audience rating may be stored for a given time unit (for example, a second, minute or hour). The audience rating management apparatus 30 may transmit information about the audience rating to other apparatuses (for example, the evaluation apparatus 10) via a network.
The audience rating management apparatus 30 may be, for example, an apparatus managed by a television audience rating surveyor. The audience rating management apparatus 30 may acquire data of viewing histories from pieces of measuring equipment connected to televisions of given households (for example, survey cooperating households) and manage the data. Note that an audience rating may be calculated or predicted from the data.
In the audience rating management apparatus 30, an audience rating for each given target (users corresponding to a given attribute) (an individual audience rating of the target) may be recorded.
Note that, in the present disclosure, targets are assumed to correspond to gender/age categories used in the field of marketing (a C (Child) layer, a T (Teen) layer, M (Male) 1 to M3 layers, and F (Female) 1 to F3 layers) but are not limited to this classification.
An example of a functional configuration and hardware configuration of each apparatus such as the evaluation apparatus 10 will be described later.
Note that the above system configuration is a mere example and the system configuration is not limited to the above system configuration. For example, for each kind of apparatus, only one is included in
A configuration is also possible in which functions of a plurality of apparatuses are realized by one apparatus. For example, at least two of the evaluation apparatus 10, the broadcast distribution apparatus 20 and the audience rating management apparatus 30 may be implemented on one server.
A spot planning evaluation method according to the embodiment of the present disclosure will be described below. Each spot planning evaluation method may be applied to the spot planning evaluation system described above.
At step S101, the evaluation apparatus 10 derives a target content rate of each advertisement slot of a certain broadcasting station (which may be replaced with a channel) for a given period (for example, one week). Note that, in the present disclosure, an advertisement slot may be replaced with a time slot, a zone or the like.
The target content rate may be calculated, for example, by Equation 1 below.
Target content rate=individual audience rating of the target/audience rating at the time of buying (Equation 1)
The target content rate may correspond to a value obtained by dividing an individual audience rating of the target by an audience rating at the time of buying. For example, if a household audience rating of a certain advertisement slot at the time of buying is 10%, and an acquired individual audience rating of the target is 5%, then a target content rate=5/10=0.5 (or 50%) may be determined. Note that, the individual audience rating of the target may mean a rate of viewers of a certain target layer relative to all individuals corresponding to the target layer.
Note that, in the present disclosure, the audience rating at the time of buying may be a household audience rating or may be an individuals' overall audience rating which is an audience rating obtained by totalizing real-time viewing and time-shift viewing during seven days after broad cast (which may be called “All&P+C7 (Program+Commercial 7)” or the like).
The evaluation apparatus 10 may acquire (for example, receive) information for deriving the target content rate. For example, the evaluation apparatus 10 may acquire information about an individual audience rating of the target, information about an audience rating at the time of buying and the like for each advertisement slot. The evaluation apparatus 10 may acquire (receive) these pieces of information from the audience rating management apparatus 30.
The information for deriving the target content rate may include information about a program to which an advertisement is assigned (which may be called program information). The program information may include, for example, a broadcast date and time (which may include start time, end time, a day of the week, time length of the program and the like), a time rank (a CM fee rank), a genre of the program, information about content of the program, keywords about the program, a predicted audience rating of the program, and the like.
At step S102, the evaluation apparatus 10 identifies advertisement slots with high target content rates. The advertisement slots with high target content rates may be called effective target zones, effective zones, ESP zones or the like (hereinafter called ESP zones).
For example, when the target content rate of a certain advertisement slot is higher than a given threshold (or a value within a given range), the evaluation apparatus 10 may judge that the advertisement slot is an ESP zone. The given threshold may be called an ESP zone threshold or the like.
Here, the given threshold (or range) may be determined, for example, from target content rates of all advertisement slots during a given period (for example, one week, one month or the like) of a certain broadcasting station (for example, may be determined as an average of the target content rates of all the advertisement slots). Further, the evaluation apparatus 10 may judge the given threshold (or range) based on an input from outside (for example, a setting by a user).
A table on the right side of
Note that, though all rates and ratings such as the target content rate and the audience rating are shown in the unit of percentage, the unit is not limited thereto.
Since the table on the right side of
In the subsequent flow, the example based on the time tables shown in
Next, at step S103, the evaluation apparatus 10 acquires acquired GRP rates by zone in a given advertisement placement pattern. Here, the given advertisement placement pattern may correspond, for example, to a normal all-day type advertisement placement pattern or other advertisement placement patterns.
An acquired GRP rate by zone may mean a rate of spot CM assignment to each advertisement slot when all the advertisement slots of the certain broadcasting station during a given period (for example, one week) is assumed as 100%. In other words, the acquired GRP rate by zone may correspond to a GRP rate expected to be acquired by each advertisement slot. The acquired GRP rate by zone may be called an acquired GRP rate, an acquired total audience rating rate, merely a GRP rate, or the like.
A table on the right side of
What is obtained by equally allocating a sum total of acquired GRP rates of each area in the table on the left side of
Next, at step S104, the evaluation apparatus 10 adjusts the acquired GRP rates by zone of step S103 based on an ESP-zone desired rate.
Here, the ESP-zone desired rate may correspond to a sum total of acquired GRP rates of all advertisement slots in the ESP zones when a sum total of acquired GRP rates of all the advertisement slots of the certain broadcasting station during a given period (for example, one week) is assumed as 100%.
In the adjustment of step S104 (which may be called acquired GRP rate control), control is performed to satisfy the sum total of the acquired GRP rates of the ESP zones=the above ESP-zone desired rate and to satisfy a sum total of the acquired GRP rates of zones other than the ESP zones=100%—the above ESP-zone desired rate.
For example, the evaluation apparatus 10 may perform the acquired GRP rate control based on Equations 2 and 3 below.
The sum total of the acquired GRP rates (before adjustment) of the ESP zones corresponds to a sum total of the acquired GRP rates of the advertisement slots in
The sum total of the acquired GRP rates (before adjustment) outside the ESP zones corresponds to a sum total of the acquired GRP rates of the advertisement slots in
For example, an acquired GRP rate (after adjustment) of the time slot between 5 o'clock and 6 o'clock on Monday corresponding to an ESP zone is determined as 0.50*80/40.5≈0.99[%] based on Equation 2.
Further, an acquired GRP rate (after adjustment) of a time slot between 13 o'clock and 14 o'clock on Monday corresponding to the outside of the ESP zones is determined as 0.80*20/59.5≈0.27[%] based on Equation 3.
At step S105, the evaluation apparatus 10 calculates effective target audience ratings of the advertisement slots based on the target content rates of the advertisement slots derived at step S101 and the acquired GRP rates by zone adjusted at step S104, and calculates a sum total of the effective target audience ratings (which may be called an effective target audience rating total, a total effective target audience rating, or the like). As the effective target audience rating total, for example, a value at the time of a given GRP value (for example 100 GRP) at which placement is assumed may be determined.
The effective target audience rating total is obtained by a sum total of the values of
At step S106, the evaluation apparatus 10 calculates an effective target audience rating cost. Here, the effective target audience rating cost may be determined by Equation 4 below:
Effective target audience rating cost=audience rating cost at the time of buying/effective target audience rating total (Equation 4)
The audience rating cost at the time of buying in Equation 4 may correspond, for example, to a cost required to acquire an audience rating at the time of buying corresponding to a given unit (for example, 1%).
The effective target audience rating total is obtained by the sum total of the values of
Note that a normal target audience rating cost may be determined by Equation 5 below:
Target audience rating cost=audience rating cost at the time of buying/target content rate (Equation 5)
According to Equation 5, it is meant that, when it is assumed that a cost to acquire a household audience rating of 1% is assumed to be 10,000 yen, and that the target content rate is 50%, the target audience rating cost is 20,000 yen.
The effective target audience rating cost in the case of not performing (omitting) the acquired GRP rate control of step S104 corresponds to a cost in spot transaction depending only on an existing placement pattern.
Therefore, by comparing the effective target audience rating cost in the case of performing the acquired GRP rate control of step S104 and the effective target audience rating cost in the case of not performing (omitting) the acquired GRP rate control of step S104, it is possible to measure a cost improvement effect based on the acquired GRP control.
The effective target audience rating total is obtained by a sum total of the values of
If it is assumed that audience rating cost at the time of buying is the same between the case of performing the acquired GRP rate control and the case of not performing the acquired GRP rate control, the effective target audience rating cost in the case of
In other words, in this case, cost reduction (efficiency) of about 13.8% can be realized by performing the acquired GRP rate control.
By performing steps S103 to S106 for each placement pattern and comparing effective target audience rating totals and effective target audience rating costs of placement patterns, the evaluation apparatus 10 may decide desirable advertisement placement (for example, budget allocation, advertisement placement patterns, ESP-zone desired rates and the like for broadcasting stations). The evaluation apparatus 10 may transmit control information for broadcasting a spot CM to the broadcast distribution apparatus 20 based on the decided advertisement placement.
According to the embodiment described above, it is possible to preferably decide highly efficient allocation of a spot CM for target.
In the spot planning shown in the embodiment described above, an example of application to a television CM is shown. However, the spot planning is not limited thereto. The above embodiment of the present disclosure may be applied, for example, to a radio CM, a CM by Internet distribution and the like. One skilled in the art can replace and understand the description of the above embodiment as necessary. For example, in the case of being applied to a radio CM, an audience rating in the present disclosure may be replaced with a listening rate.
Here, “GRP” in the present disclosure may be replaced with any other index about a total audience rating.
Note that the present disclosure covers content in which “audience rating” is replaced with a particular index (or a degree of improvement, offset or the like of a particular index). The particular index may be an index for judging advertisement effects, an intermediate index for improving KPI (key performance indicators) of an advertiser, or the like, and, for example, a recognition rate, reach, ROAS (Return On Advertising Spend), ROI (Return on Investment) and the like may be included. A part of mentions of “audience rating” may be replaced with any of the above particular indexes.
For example, the target content rate in Equation 1 may be replaced with Equation 6 or Equation 7 below.
Target content rate=particular index per target individual/particular index for the whole at the time of buying (Equation 6)
Target content rate=particular index per target individual/audience rating at the time of buying (Equation 7)
Further, the present disclosure covers content in which “target” and “of the target” are deleted. When replacing with the particular index, which has been described above, is considered, for example, the content rate of the present disclosure may be replaced with Equation 8 below. By doing so, it can be expected to improve advertisement effects of an advertiser based on ESP zones irrespective of a target.
Content rate=particular index/particular index at the time of buying (Equation 8)
If replacement of terms stated here is applied, other terms may be appropriately replaced. For example, the acquired GRP rate may be called an acquired index rate or the like; the effective target audience rating may be called an effective target index, an effective index or the like; and the audience rating cost may be called an index cost or the like.
