1. A method comprising:
detecting a first watermark corresponding to a first media presentation;
associating the first watermark with an ongoing media presentation record in a watermark data structure when the ongoing media presentation record corresponds to the first media presentation;
detecting a second watermark;
determining that the second watermark corresponds to a second media presentation different than the first media presentation;
updating, based on the determining, the ongoing media presentation record in the watermark data structure to end at a time corresponding to the first watermark being detected to form a previously-presented media presentation record;
generating, based on the determining, a new ongoing media presentation record associated with the second media presentation and the second watermark; and
starting a bridge timer for the new ongoing media presentation record,
wherein the bridge timer tracks a bridge time which corresponds to a duration of time since the detecting of the second watermark, and
wherein the bridge timer is used to determine when the new ongoing media presentation record ends.
