The number of households tuned in to a given program at a given time.

• A. Audience
• B. Reach
• C. Shares
• D. Ratings

Answer: (C)

Focusing on a snapshot of viewing at a specific moment, the share measures how many households are watching a program relative to all households currently using their TV. It represents the proportion of current TV viewers tuned to that program, usually shown as a percentage. This is why it fits the prompt “the number of households tuned in to a given program at a given time”—the share reflects that audience size as a portion of the active TV-watching pool. For example, if 250 households are watching and 4,000 households are using TV at that moment, the share is 250/4000 = 6.25%. The audience would be the raw 250 households, ratings would relate to all households with TV in the market, and reach covers unique viewers over a period.
