Whether or not Google should proceed with placing ads in in-flight entertainment depends on a few factors. First, they would need to consider the potential revenue that could be generated from these ads. This would involve analyzing the size of the market and the potential reach of the ads. If the revenue potential is high, it may be worth moving forward with the idea. Second, they would need to consider the impact on the user experience. If the ads are intrusive or take away from the overall experience, it could lead to negative feedback from users. On the other hand, if the ads are well-integrated and provide value to users, it could enhance the overall experience. Finally, they would need to consider any potential legal or ethical issues. For example, if the ads are targeted based on personal data collected from passengers, it could raise privacy concerns. Given these factors, Google should proceed with caution and conduct thorough research and testing before implementing any ad placements in in-flight entertainment. It may also be worth considering alternative revenue streams or partnerships that could provide value to users without detracting from the experience.
