According to Nielsen, 1,475,493 adults tune in to their favorite Las Vegas radio stations every week. This is significantly more consumers than are reached by all other advertising-supported media, including local TV, local cable, streaming video, social media, online audio, and local newspapers.

Las Vegas radio's unchallenged reach is why many local business owners depend on the medium to capture the largest possible share of the $45.1 billion dollars consumers are expected to spend at retail this year.

Other local small business owners, however, may be surprised to learn that by most marketing metrics, radio remains the best way to advertise in Las Vegas.

Here are four more facts about AM/FM radio that may surprise many local marketers.

Since 1930 when KGIX-AM signed on, local small business owners have been advertising on Las Vegas radio to market the goods and services they sell.

Lately, some of these advertisers are voicing concerns, though, that the accelerating use of smart speakers could erode the effectiveness of commercials on local stations. Current research, however, reveals that these devices actually extend the reach of the medium and its ad content.

More than 472,150 consumers in Las Vegas have a smart speaker in their homes, according to Nielsen. This is 26.5% of the local adult population.

Smart speakers are internet-enabled devices controlled by spoken commands and capable of streaming audio content, relaying information, and communicating with other devices. 

According to the Cooperative Institutional Research Program (CIRP) data, Amazon Echo (aka Alexa) accounts for 69% of all smart speakers in use. Google's smart speaker makes up another 20% of the market. The remaining 11% of the market comprises Apple Home (aka Siri), Sonos, and Bose.

Las Vegas consumers can use their smart speakers to accomplish a diverse range of tasks, including accessing news, weather, and sports information; turning on lights in the house; shopping; and food delivery.

The most common use of a smart speaker, though, is streaming audio, including Las Vegas radio stations, according to eMarketer. Edison Research's Share of Ear Study indicates that consumers devote 13% of their total time using a smart speaker listening to AM/FM radio stations. This is second only to the time spent listening to Amazon Music at 19%.
