Methods and apparatus for detecting and correlating content consumption, e.g., viewing of programs and/or accessing websites, across platforms of different types are described. Content consumption, e.g., requests and/or streaming is monitored and recorded on a per subscriber basis for a wide variety of platforms, e.g., set boxes, IP content playback devices such as cell phones or pad devices with IP streaming support, and/or other devices. Web site access and corresponding content consumption is determined based on DNS requests thereby avoiding the need for monitoring at web site servers and allowing centralized monitoring of web site access operations in the form of DNS requests to be detected by a Web service provider who, at least in some embodiments, is also a content provider.
