Love them or hate them, wearables are here to stay. With the Apple Watch having launched in April, we are past the point of no return when it comes to the next evolution of devices. Along with the new screens that wearables provide, we’re starting to see the beginning of the wearable ad era.

A recent report from Juniper Research, Digital Advertising: Online, Mobile & Wearables 2015-2019″ lays out the ramp-up to wearable saturation that we’ll be seeing in the coming years.tm0615_smartwatch_graph.jpg

Even though the chart on “Total Smartwatch Advertising Spend” starts at $0 in 2014, it certainly doesn’t stay there. Marketers are facing an incredible CAGR (compound annual growth rate) of 341 percent from 2014 to where it is projected to be in 2019. If everything continues under current trends, annual smartwatch advertising spend will clock in just shy of $70 million annually.

Even though it’s still early in the game, it’s not too soon to be thinking about how smartwatches and wearables can be integrated into your marketing mix. There’s still plenty of time before market saturation — but it’s definitely something to watch.
