An example includes a segment collector to: access impression records indicative of media access segments, the media access segments including start times and end times corresponding to media accessed by a panelist; and determine ones of the impression records that include a watermark corresponding to a first media platform presenting the media; a segment classifier to convert a first one of the impression records including the watermark to a converted impression record; and combine the converted impression record corresponding to the first media platform and a second impression record corresponding to a second media platform; and a media creditor to generate audience measurement metrics based on the combined impression records.

Methods and apparatus for determining audience metrics across different media platforms

Methods, apparatus, systems and articles of manufacture are disclosed for determining media access sessions. In an example, an apparatus to determine media access sessions includes a record locator to access, in a data store, a first media impression record indicative of a first media access segment, and a second media impression record indicative of a second media access segment and a view counter. The view counter is to update at least one of the first or second media impression records in the data store, when the second media access segment occurs within a threshold time after the first media access segment, to indicate that the first and second media access segments are associated with a same first media access session. The view counter is also to update the second media impression record to indicate an association between the second media access segment and a second media access session, when the second media access segment occurs more than the threshold time after the first media access segment, the second media access session being different from a first media access session corresponding to the first media access segment.
