Final answer:
The correct answer is that advertisers reach their targeted audiences through in-game ads, product placements, sponsored content, and advergames. This shift to gaming platforms responds to declining effectiveness of traditional TV and print media advertisement.
Step-by-step explanation:
Among the four main ways advertisers use games to reach their targeted audiences, creating in-game ads, product placements, sponsored content, and advergames are included. These methods have been adopted due to the significant decline in advertising revenue from more traditional mediums like television and print media, as more consumers are finding ways to bypass these advertisements. In the ever-evolving landscape of media, advertisers are increasingly turning to the gaming world, where they can engage directly with users, often in ways that blend smoothly with the gaming experience and hold the gamers' attention more effectively than traditional advertising tactics.
