The Relationships of Governments and Inudstry

Why silicon valley can't fix itself was my long read and it had me thinking about the relationships between the government and companies or industries. As I was inspired by an image in the article which was a picture of Mark Zuckerberg testifying before the senate  These relationships vary from place to place and depending on what terms the government wants to do and how powerful it is, a company can either do whatever it wants, becomes a tool of the government, and or become threatened by the government. These all can have various results depending on how the situation is handled, these can all happen within one country's history depending on how the government handles them, which can change on the basis of how it is swayed, either by public opinion or by the elite. Using the United States as an example there are many instances where these relations were put into question such as in the 1990s there were many complaints by parents because of violent content in video games such as Mortal Kombat, because it was at a time where this content in video games wasn't rated or monitored at all and anyone could just buy it including children. These complaints resulted in congressional hearings creating a threat of potential government oversight of video game ratings. The established the ESRB within it to create a voluntary rating system based on the Motion Picture Association of America film rating system.  This voluntary part of this is however strictly enforced in the industry as if it weren't the government would have to step in and there are many agreements among the industry to uphold the rating system. It is voluntarily enforced by the associated industries such as video games and retail for physical release. This can be seen when if one was to purchase a game carrying the ESRB's highest age ratings you are asked to present identification by stores in order to purchase those games. Stores also do not stock games that have not been rated. Console manufacturers will not license games for their systems unless they carry ESRB ratings. However, there are also voluntary restrictions by the industry to games of a certain rating, such as adult-only rated games aren't stocked by console manufacturers and stores. As to not have adult-only content being further restricted from the eyes of children. In short, the history of the ratings of videogames at first was a free reign, but due to various pressures and threats by the government the ESRB was created to control these practices to appease the government as a helpful tool to regulate industry practices by itself before the situation further escalated. Do you know of any other instances where the government had to step into industry? Of any other complex and changing relationships between government and industry?
