Like most years, 2014 has gone by in a flash, it seems. But like many years before it, it will leave its own mark on the development of new markets and tech businesses as well as the decline of others. Below is a list of my personal Top 20 trends and disruptions in terms of their significance this year, and for 2015 and beyond. It should come as no surprise that, to put it mildly, my Top 20 draws on some of the companies and topics I covered in posts during the year, because these represent themes and issues that I was able to explore in some detail

The 2014 Consumer Electronics Show (CES) has come and gone. Vendors demonstrated how wearables, 4K OLED TVs, and 3-D printing, among many other categories, would change our lives. And no doubt one day some of them will. But not so fast. Lots of cool stuff, but for some categories, mass consumer adoption lies further down the road. Although these "consumer" products are being launched at the CES, in order to cross the chasm many of these are in reality going to be selling to business for some time to come. The Technology Adoption Life Cycle (TALC) can serve as a compass for how to navigate the waters of both consumer and business adoption. For disruptive innovations, consumer adoption may eventually happen, but only after the category crosses the chasm in business.
