Step-by-step explanation:
Today, the most dominant source for political information is the internet. With the advent of digital media, there has been a significant shift from traditional mass media platforms such as print, radio, and television to online sources. According to research findings from the Pew Research Center, an increasing number of people, particularly the younger generation, are turning to digital sources to stay informed. This trend has grown over the years due to the ease of accessing news on smartphones and tablets. Moreover, social media platforms have become a cornerstone of modern political communication, allowing for instant information sharing and public discussion. Additionally, the shift to online news consumption has dramatically affected print media, reducing its role as the primary source of news for most Americans.
