How can global companies like Apple or Google use public sentiment to improve their PR strategies?

Yes, a notable example is the Tylenol crisis in 1982. Johnson & Johnson, the parent company of Tylenol, faced a major PR crisis when seven people in Chicago died after taking Tylenol capsules that had been laced with cyanide. The company's response is often cited as an example of excellent crisis management. They immediately pulled 31 million bottles of Tylenol off the shelves, which cost them more than $100 million. They also introduced tamper-proof packaging and ran an extensive media campaign to restore public trust. As a result, they successfully managed to rebuild their brand and regain consumer trust.

There are several alternative methods to handle a major PR crisis and monitor public sentiment over time. One of the most effective methods is to use social listening tools to track public sentiment in real time. This can help you understand the public's perception of your brand and respond to any negative sentiment quickly and effectively. Another method is to use crisis management software, which can help you manage and respond to a crisis in a timely and organized manner. Additionally, conducting regular surveys and focus groups can also provide valuable insights into public sentiment. Finally, maintaining open and transparent communication with the public during a crisis can help to rebuild trust and improve public perception over time.
