Abstract: Methods and apparatus to identify media based on watermarks across different audio streams and/or different watermarking techniques are disclosed. An example apparatus includes a watermark detector to detect a first watermark embedded in a first audio stream associated with media and to detect a second watermark embedded in a second audio stream associated with the media. The second audio stream is different than the first audio stream. The example apparatus includes a watermark analyzer to compare first media identifying information in the first watermark with second media identifying information in the second watermark. The example apparatus also includes a media detection event controller to associate the first and second watermarks with a media detection event when the first media identifying information is consistent with the second media identifying information. The example apparatus further includes a transmitter to transmit the media detection event to a data collection facility.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for identification of local commercial insertion opportunities. Example apparatus for identification of local commercial insertion opportunities include a media comparator to compare respective instances of media conveyed in respective ones of a plurality of broadcast signals associated with affiliates of a national broadcaster to identify a broadcast interval having different media conveyed among at least some of the broadcast signals. The example apparatus also include an insertion opportunity identifier to determine whether the broadcast interval is associated with a local advertisement insertion opportunity based on a characteristic of the broadcast interval.
