Wearable tech may seem like a fad to some people, but there’s no question that it’s quite popular – and could become even more so over the next few years.

A report from Advertising Age indicates that wearable tech devices could see a huge increase in sales, with an increase of 704.5 percent between 2013 and 2018. Smartwatches lead the charge in this sales push, thanks to its capability of becoming an ad platform.

Last year, over 22 million purchased items involving wearable tech, but Cisco Systems expects that number to rise to 177 million in 2018, including possible offerings from Samsung and Apple.

Average monthly mobile data traffic could grow as a result as well, rising from 67 MB per month last year to 345 MB in 2018.
