MPEG DASH was created to deal with a highly fragmented media streaming ecosystem struggling with fragmentation and lack of interoperability of many proprietary solutions. Still that fragmentation has not stopped video to grow to being over half of mobile, and almost three-quarters of fixed traffic (YE2012). But this situation very negatively impacts on the one hand technology scale and cost advantages in the industry, and on the other hand the end user experience, engagement and (advertising) revenues that keep the media wheel spinning.
Enter MPEG DASH - the industry-defined open standard for media streaming that has gained strong industry support. Many suppliers have announced support for MPEG DASH though broad, real-world deployment is still a few years out.
