Pick an ad-supported niche content provider (e.g., a website or cable channel) that caters to a demographic niche (e.g., age, race, gender, or sexuality). How does it present the value of the niche to advertisers? How does it define who is included as part of this niche? How has this changed over time? How does it represent its niche in its content choices? Again, how has this changed over time? Ultimately, what does your case study reveal about constructing an audience in niche economics?
