Examples of companies losing public trust & How did they overcome/regain it?

Hello, I am looking for some examples of companies who were involved in PR scandals and lost public trust but were able to eventually regain it. There are a lot of examples of companies losing public trust but there are less so for companies that have regained it. As such, I'm looking for more examples as I am primarily concerned with strategies the companies took in response to negative PR. All help is appreciated, thank you. via /r/business https://ift.tt/2KmPGOS
