Are websites optimized for mobile devices and Smart TVs?

The purpose of this study is to evaluate the adaptation of some of the world´s most popular Web sites to the “post-pc era” of using multiple devices for accessing the Web. Up till recently the PC used to be the only device used for accessing the WWW. This has changed dramatically over the past few years with the introduction of many powerful Internet-connected devices such as Smart Phones, Tablets and Smart TVs. Due to the many differences between these devices in terms of screen size, hardware power, input methods etc. in most cases a PC-optimized Web site is not optimally viewed in these devices, resulting in poor usability and User Experience. In this survey 49 of the world´s most visited Web sites, according to Alexa.com, are being examined to see if they offer optimized versions for Internet-connected mobile devices and Smart TVs. Results show wide support for mobile devices in contrast to very limited support for Smart TVs.
