Answer

Brief Explanations:

To determine how public service campaigns have changed over time, we analyze each option:

  • Option 1: As technology and media evolve, advertisers integrating new media (like social media, digital platforms) into public service campaigns is a key change over time.
  • Option 2: Sponsors selling media access is not a typical change in public service campaigns (they aim to inform/educate, not commercialize access).
  • Option 3: Governments have long sponsored public service announcements, so this is not a new change over time.
  • Option 4: While appeals/arguments may evolve, the integration of new media/tech is a more prominent and widespread change in how campaigns are executed.

Answer:

A. Advertisers have integrated new media and technologies.
