Advertising on flights can be an attractive opportunity for any company looking to expand their advertising reach. However, for a company like Google, the decision to enter the in-flight advertising business would require careful consideration of various factors. First and foremost, Google would need to assess the potential market size and demand for in-flight advertising. They would need to evaluate the current players in the market and determine whether there is room for a new entrant. Additionally, they would need to consider the types of airlines that would be interested in their services, as well as the target audience of these airlines. Another factor to consider is the logistics of implementing an in-flight advertising system. Google would need to work with airlines to ensure that their technology is compatible with existing in-flight entertainment systems. They would also need to consider the costs associated with installing and maintaining their advertising system on each plane. Furthermore, Google would need to consider the potential impact on the user experience. In-flight advertising can be intrusive and disruptive, and Google would need to develop a system that balances the desire to display ads with the need to provide a quality user experience. Overall, while the in-flight advertising business may present an attractive opportunity for Google, it is important that they carefully evaluate the potential market size, logistics, and impact on the user experience before making a decision to enter the market.
