What significant event occurred on February 17, 2009, regarding television broadcasts in the US?

On February 17, 2009, a pivotal moment in the history of television broadcasts in the United States occurred with the termination of all analog transmissions by full-service TV stations. This decision marked the nationwide transition from analog to digital television, which was part of a larger initiative to improve the quality and efficiency of broadcast signals. The switch to digital broadcasting allowed for better picture quality, more channels, and enhanced services such as high-definition broadcasting.

By discontinuing analog transmissions, the Federal Communications Commission (FCC) aimed to free up valuable electromagnetic spectrum that could be repurposed for other communications services, including public safety communications and broadband internet. This event significantly impacted millions of viewers, as those using analog TVs without a converter box were required to make adjustments to continue receiving television programming. The transition to digital also necessitated new equipment, education, and outreach efforts to ensure that audiences were informed and prepared.
