Abstract
Methods and apparatus for collecting media consumption data based on usage information of a media delivery device are disclosed. In an example method, media information is received by a portable metering device associated with a monitored individual such as a portable telephone, a personal digital assistant, and/or a handheld computer. Usage information indicative of a media delivery event associated with a media delivery device such as a television is monitored by the portable metering device. To form the media consumption data, the media information is associated with one of a first channel and a second channel based on the usage information.
