Step-by-step explanation:
The spread of information exposed Americans to new ideas through various means, including communication of information, cultural exchange through media, transportation of data, and the transfer of knowledge through technology. Each wave of technological innovation, from the printing press to the Internet and smartphones, has greatly facilitated the dissemination of information. Innovations like radio, television, fax machines, and social networks have played pivotal roles in sharing news and spreading cultural influence worldwide, impacting the ways Americans and people globally communicate, work, learn, and engage with each other. Notably, technological advancements have often occurred in the face of resistance from those in power who attempted to control or censor information.
