Step-by-step explanation:
When TV took over radio's role as the primary source of American entertainment, it had a significant impact on society. Television brought visual media into people's homes, revolutionizing the way information and entertainment were consumed. People could now watch news events and shows in real-time, creating a shared experience across the country. Regional differences in dialect, language, music, and consumer taste were smoothed out as Americans from coast to coast could watch the same programming. Additionally, television transformed sports entertainment by broadcasting play-by-play descriptions of sporting events.
