The FCC points out that using such tones is prohibited outside of emergencies, adding that it was a serious public safety concern. “These rules aim to protect the integrity of the alert system by helping to avoid confusion when the tones are used, alert fatigue among listeners and false activation of the EAS by the operative data elements contained in the alert tone,” it explained in a news release.

ABC told the FCC that there was a “misunderstanding that the use of the tone was permissible.” The network has reportedly removed the part of the episode featuring the tones from YouTube and elsewhere, and elected to not rebroadcast the episode.

While the idea of the skit was amusing, government officials said last year that neither Trump nor any other president could “wake up one morning and attempt to send a personal message” using the system. Earlier this month, FEMA conducted a real emergency alert test to confirm that it would work if there was power but no internet.

The lawsuit also alleges that Locast exists to help AT&T and Dish avoid paying to carry broadcast content. Both DirectTV and Dish customers are directed to Locast on their set-top box menus. The lawsuit claims that when Locast retransmits signals, the broadcasters lose out on vital viewership information.

In its defense, Locast says its nonprofit status allows it to operate as a “booster” and strengthen a TV station’s signal to reach antennas. But as The Wall Street Journal points out, the fees broadcasters receive from pay TV distributors have become crucial to their survival. If Locast continues to grow, it could put a significant dent in the networks’ revenue. Launched in 2018, the service already reaches 35 million homes in 13 cities — an estimated 31 percent of the market.

This case may remind you of another. In 2014, broadcasters accused Aereo of copyright infringement. Aereo charged customers $8 per month to rent a physical antenna that offered local channels and cloud DVR service streamed to smartphones, tablets and computers. But broadcasters and the federal government claimed that was a violation of copyright law, as re-broadcasting content from the airwaves via the internet is not allowed. In the end, Aereo was forced to pay broadcasters $950,000. It’s too soon to guess whether Locast will face a similar fate.
