Systems and methods for measuring media performance on end-user devices

A system comprising:

• one or more processors;
• a network connection;
• and
• data storage that is operatively coupled to the one or more processors, wherein the data storage stores instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, via the network connection, first data identifying a time interval between a value of a first timestamp and a value of a second time stamp, the first timestamp and second timestamp obtained consequent to a script executing on a browser, the script when executed, executing operations to:
• send, to the browser, a first request to call a specified function to update an animation;
• receive, consequent to sending the first request, the value of the first timestamp;
• store the value of the first timestamp;
• send, to the browser, a second request to call the specified function to update the animation;
• receive, consequent to sending the second request, the value of the second timestamp;
• receiving, via the network connection, second data comprising an identifier of a first sponsored content item associated with the animation;
• receiving, via the network connection, third data comprising a parameter of a platform displaying the animation;
• generating an updated value of a metric of the first sponsored content item based on the time interval above a predetermined value of the time interval;
• storing the updated value of the metric and an association of the updated value of the metric with the first sponsored content item and the third data;
• receiving a request for a sponsored content item, the request comprising data matching a value of the third data;
• selecting a second sponsored content item other than the first sponsored content item based on the updated value of the metric associated with the first sponsored content item and the third data;
• transmitting, via the network connection, the second sponsored content item.

A non-transitory computer-readable storage media storing instructions that are executable by one or more processing devices to perform operations comprising:

• receiving, via a network connection, first data identifying a time interval between a value of a first timestamp and a value of a second time stamp, the first timestamp and second timestamp obtained consequent to a script executing on a browser, the script when executed, executing operations to:
• send, to the browser, a first request to call a specified function to update an animation;
• receive, consequent to sending the first request, the value of the first timestamp;
• store the value of the first timestamp;
• send, to the browser, a second request to call the specified function to update the animation;
• receive, consequent to sending the second request, the value of the second timestamp;
• receiving, via the network connection, second data comprising an identifier of a first sponsored content item associated with the animation;
• receiving, via the network connection, third data comprising a parameter of a platform displaying the animation;
• generating an updated value of a metric of the first sponsored content item based on the time interval above a predetermined value of the time interval;
• storing the updated value of the metric and an association of the updated value of the metric with the first sponsored content item and the third data;
• receiving a request for a sponsored content item, the request comprising data matching a value of the third data;
• selecting a second sponsored content item other than the first sponsored content item based on the updated value of the metric associated with the first sponsored content item and the third data;
• transmitting, via the network connection, the second sponsored content item.
