The subject disclosure relates to a computer system and method for automatically optimizing selection of media units.
“Linear television” refers to television (TV) that is watched with the originally broadcast advertising inserted in ad breaks, including live pre-recorded and video on demand (VOD). This is in contrast to dynamically inserted advertising, also referred to as addressable. The TV advertisement marketplace consists of buyers (e.g., TV advertising agencies) and sellers (e.g., TV content producers and distributors). A linear TV advertising campaign includes a series of video clips (each of which is referred to as a “creative”) placed in available time slots that sellers sell to buyers. Three related quantities describe, at a high level, the effectiveness of a linear TV advertising campaign: impressions, reach, and frequency. For example, if 10 people watch a particular creative, and each such person watched that creative two times over the course of an advertising campaign, then the campaign will have a reach of 10 people, collect 20 impressions, and have an average frequency equal to 2. The mathematical relationship between these three quantities is:
Impressions=Reach*Average Frequency (1)
The quantity “impressions” may be replaced by another quantity that typically is referred to as ratings, which are the ratio of impressions to the estimated size of the target segment (also referred to as the “universe estimate”), expressed as a percentage. In the example above, if the estimated size of the target segment is 1,000, then the rating is 2 (100×20/1,000). In the description herein, impressions and ratings may be used interchangeably unless otherwise noted.
An advertiser (buyer) typically is interested in maximizing impressions, subject to a number of constraints, such as budget, dates, times of day, separation between transmission times, and combination of TV networks, channels and programs, among others. Since these constraints specify absolute or relative minimum and maximum limits on the fraction of the budget to spend on, or impressions to collect from various potential ad placements, they effectively limit the maximum value of impressions for a particular TV campaign. Maximizing impressions within these constraints can however deliver excessive frequency, with some persons being exposed a very large number of times to the advertising. This may make those viewers turn away from the advertised product or service, and thereby achieve a result that is the opposite of that desired and intended by the advertiser. The ideal outcome, from the advertiser's perspective, is one which balances reach and average frequency. In some cases this may mean maximizing impressions, in some cases this may mean maximizing reach, and in other cases this may mean finding a solution somewhere between these.
Achieving such a balance between reach and average frequency efficiently and in a wide range of cases is a challenging problem.
Reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
In various embodiments, a computerized system automatically optimizes an advertising campaign in a variety of ways, such as optimizing for the ratings of the advertising campaign or by optimizing for the reach of the advertising campaign. Such automated optimization enables advertisers to achieve their goal, subject to the constraints of the advertising campaign (such as the budget and target networks of the advertising campaign).
For example, various embodiments can perform optimization which:
In various embodiments, users can employ disclosed mechanisms to perform optimization according to one or more of the optimization goals (a, b, c) described above. It may be reasonable, for example, for the user to select the “reach only” optimization goal first. The reach obtained by applying the “reach only” optimization goal, however, is usually higher than the reach obtained by applying the “reach and ratings” optimization goal, although at the cost of fewer rating points than the “reach and ratings” optimization goal. A user may, therefore, wish to employ mechanisms (such as described herein) to perform multiple optimization goals (e.g., a, b and/or c above), to compare the results and/or to select one of the optimization goals based on the user's preference for reach in comparison to ratings.

The method 200 initializes an iteration count I to zero (
The system 100 includes a constraint initialization module 102, which initializes and outputs a set of constraints 104 (see also,
The system 100 also includes a scheduler 106, which receives the constraints 104 as input, and which generates a schedule 108 as output that maximizes impressions and satisfies all of the constraints 104 (see also,
The system 100 also includes a reach calculation module 110, which receives the schedule 108 as input, and which calculates a reach 112 based on the schedule 108 (see also,
The system 100 also includes a constraint control module 114, which receives the constraints 104 and the reach 112 and average frequency as inputs, and which modifies the constraints 104 based on the other inputs to produce modified constraints 116 as output (see also,

Note that instead of iterating N times, the method 200 can instead iterate until at least some predetermined amount of time has passed since the method 200 began. This can be implemented, for example, by initializing a timer in operation 201 instead of a counter, and by determining, in operation 210, whether the current value of the timer (which can increase in value in correspondence with the passage of time) is greater than or equal to some predetermined maximum amount of time.
As yet another example, the method 200 can instead terminate when the rate of change in the reach 112 falls below some predetermined threshold value, where the rate of change in the reach 112 can be measured, for example, by the difference in value of the reach 112 from one iteration of the method 200 to the next (over two or more such iterations).
Regardless of the termination criterion that is used, the most recently produced schedule, or the “best” schedule according to some qualitative and quantitative criteria, or a subset of all the produced schedules by the system 100 and method 200 when the method 200 terminates is output by the system 100 and method 200 as their final output.
A wide variety of scheduling techniques are known in the art, and the scheduler 106 can use any of a variety of techniques. In addition, however, in various embodiments, the scheduler 106 uses improved techniques which enable the system 100 and method 200 to significantly improve the resulting schedule 108, as measured by the coverage of the advertising in the schedule 108, where “coverage” refers to the number of persons or homes that fall within the desired target that are exposed to at least one airing of the schedule 108.
In general, the scheduler 106 implements a scheduling algorithm which executes a loop in which only some of the constraints 104 differ from one iteration of the loop to the next. Various embodiments can make this feature as efficient as possible by indexing the right hand sides of the constraints 104 (in particular upper limits). The constraints (within the constraints 104) that need modification may not be contained in the initial formulation of the problem (e.g., may not be part of the set of the user-provided constraints), but may instead be added to the constraints 104 by the reach optimization process based on the contents of the cartesian product of the inventory and the campaigns being scheduled.
As a specific example, each of the constraints 104 can include the following parameters, each of which can have a corresponding value:
The set of parameters listed above is merely an example and does not constitute a limitation. Various embodiments can use constraints having parameters other than those listed above.
In various embodiments, the constraint control module 114 can only make modifications to the constraints 104 which relax those constraints 104. In various embodiments, the scheduler 106 can place a non-integer number of advertisements in a single slot in intermediate iterations of the method 200, but not in the final iteration of the schedule 108 that is output by the method 200 (i.e., such a final iteration of the schedule 108 only contains integer numbers of placements in the slots in the schedule 108 in such embodiments).
As described above, although various embodiments may optimize for different goals, the system 100 and method 200 shown and described in connection with
First, consider an example in which the set of constraints 104 under the control of the method 200 is represented by the following table, which also shows the reach and average frequency decomposition:
The constraint control module 114 can calculate, based on a table such as the one above, the mean average frequency from the values in the columns target_impressions, and target_reach, e.g., mean_avg_frequency=(2700+2340+7000)/(1000+1300+2000)=2.8.
The constraint control module 114 can calculate, for each network-daypart in a table such as the one above, a maximum number of impressions (max_target_imps_at_mean) targeting a frequency equal to the mean_avg_frequency. The following table illustrates an example of the results of such calculations of the value of the column max_target_imps_at_mean, which involves, for each network-daypart (i.e., row in the table below), dividing the value of target_impressions by the value of mean_avg_frequency (which is equal to 2.8 in this example):
The constraint control module 114 can, for each network-daypart, calculate the corresponding reach proportion, which involves, for each network-daypart (i.e., row in the table above), dividing the value of target_reach for that network-daypart by the sum of all of the values of target_reach in the table:
The constraint control module 114 can, for each network-daypart, calculate a proportional number of impressions collected at the same rate as reach, by multiplying the sum of all values of target_impressions in the table by the value of reach_proportion for that network-daypart. This quantity will be referred to herein as max_prop_target_imps.
The constraint control module 114 can determine which of the constraints 104 to control in the current iteration. This can be performed, for example, by selecting the network-dayparts for which the value of avg_frequency>mean_avg_frequency. An example of this is shown in the table below, in which network-daypart 4 is selected for constraint control because its avg_frequency is greater than the value of mean_avg_frequency:
The next step, which produces as output a list of constraints (e.g., constraint IDs) to be modified by the constraint control module 114 and the new values of such constraints, can vary depending on whether the system 100 and method 200 are optimizing for reach only or for both reach and ratings. In either case, the list of constraints to be modified can be generated in the manner described above.
If the system 100 and method 200 are optimizing for reach only, then the constraint control module 114 can calculate the new maximum limit of the selected constraints by choosing the maximum of max_target_imps_at_mean and max_prop_target_imps for each of the selected constraints. For example, using the values in the tables above, this would result in the following new maximum values for the selected constraints (i.e., network-daypart 4 in the example above):
If the system 100 and method 200 are optimizing for both reach and ratings, then the constraint control module 114 can calculate the new maximum limit of the selected constraints by: (1) selecting the constraint that has not been modified in any way during the previous iterations (from among the constraints selected above) with the maximum average frequency and (2) setting the new max_value of that constraint to be equal to the value of max_target_imps_at_mean.
Regardless of which of these two methods are used to select the new maximum values of the modified constraints 116 in the next iteration of the method 200, the method 200 can then continue to the next iteration in the manner described above.
The final output of the system 100 and method 200 is the version of the schedule 108 which has the highest reach, regardless of the iteration of the method 200 at which that version of the schedule 108 is found. As this implies, the version of the schedule 108 that is output by the system 100 and method 200 may not be the version of the schedule 108 that is produced in the final iteration of the method 200. As this further implies, during each iteration of the method 200, the system 100 and method 200 can compute the full reach of the schedule 108 in addition to computing separate reaches for each network-daypart in the schedule 108.

As described herein, various embodiments can provide for iterating (e.g., changing constraints and/or changing constraint values).
As described herein, various embodiments can provide for: (a) initial selection of advertisements across different networks/dayparts; (b) identifying where there is waste (e.g., too many advertisements and/or too much frequency); (c) optimizing—for example, put (e.g., daypart units) somewhere else to increase reach; (d) iterating (b), (c) and/or (d).
In one embodiment, a method comprises:
In one example, (B) above comprises optimizing the advertising schedule for both reach and ratings.
In another example, (B) above comprises optimizing the advertising schedule for reach only.
In another example, (B) above comprises optimizing the advertising schedule for ratings only.
One advantage of various embodiments is that such embodiments can deliver a key advertising requirement, namely improved coverage of an advertising target. Various embodiments satisfy this requirement automatically in a real world application, using a media owner's actual available inventory, and selecting the schedule's units in minutes. The size of the inventory (often ˜tens of thousands of possible ad placements) and the number of constraints targeted by a campaign (often ˜thousands of constraints) can make the computations described herein impractical via mental/manual methods.
As described herein, various embodiments can provide a computerized system that automatically optimizes an advertising campaign in a variety of ways, such as optimizing for the ratings of the advertising campaign or by optimizing for the reach of the advertising campaign. Automated optimization provided by various embodiments enables advertisers to achieve their goal, subject to the constraints of the advertising campaign, such as the budget and target networks of the advertising campaign
It is to be understood that although particular embodiments have been described, such embodiments are provided as illustrative only. Various other embodiments, including but not limited to the following, are also within the scope of the claims. For example, elements and components described herein may be further divided into additional components or joined together to form fewer components for performing the same functions.

A human, therefore, would find it overwhelming and, as a practical matter, impossible to schedule (using mental and/or manual processes only) a large number of television advertisements within the applicable temporal and other constraints.
