Final answer:
The passage addresses an audience of media studies enthusiasts, academics, students, and professionals focused on media consumption and cultural identity, showing examples of audience targeting in President Johnson's speech and various literary works.
Step-by-step explanation:
The passage likely addresses an audience interested in media studies and the nuances of audience engagement with mass media. Considering the context of S.E. Bird's book The Audience Everyday Life: Living in a Media World, the passage speaks directly to academics, students, and professionals who are keen on understanding the ethnographic and qualitative aspects of media consumption and its influence on individual and cultural identity formation. Similarly, President Johnson's speech at the University of Michigan, targeting both attendees and a broader national audience, further illustrates the concept of audience tailoring in communication. Furthermore, fictional or poetic texts, like Sondheim's musical and the excerpt from a poem about a bird, also cater to specific audiences through their literary form and content.
