The vast amount of data marks an unparalleled period in time and is one of the major contributing factors that has led the world into the Zettabyte Era. YouTube is another large video streaming (and video uploading) service, whose data consumption rate across both fixed and mobile networks remains quite large. In 2016, the service was responsible for using up about 20% of total Internet traffic and 40% of mobile traffic. In 2016, 100 hours of video content on YouTube was uploaded every 60 seconds. YouTube not only offers content for download (through streaming) but also As of 2018, 300 hours of YouTube video content is uploaded every minute. The usage of mobile technologies to access IP networks has resulted in an increase in overall IP traffic in the Zettabyte Era. In 2016, the majority of devices that moved IP traffic and other data streams were hard-wired devices. Since then, wireless and mobile traffic have increased and are predicted to continue to increase rapidly. Cisco predicts that by the year 2021, wired devices will account for 37% of total traffic while the remaining 63% will be accounted for through wireless and mobile devices. Furthermore, smartphone traffic is expected to surpass PC traffic by 2021; PCs are predicted to account for 25% of total traffic, down from 46% in 2016, whereas smartphone traffic is expected to increase from 13% to 33%. According to the Organisation for Economic Co-operation and Development (OECD), mobile broadband penetration rates are ever-growing. Between June 2016 and December 2016 there was an average mobile broadband penetration rate increase of 4.43% of all OECD countries. Poland had the largest increase coming in at 21.55% while Latvia had the lowest penetration rate having declined 5.71%. The OECD calculated that there were 1.27 billion total mobile broadband subscriptions in 2016, 1.14 billion of these subscriptions had both voice and data included in the plan. Broadband is what connects Internet users to the Internet, thus the speed of the broadband connection is directly correlated to IP traffic – the greater the broadband speed, the greater the possibility of more traffic that can traverse IP networks. Cisco estimates that broadband speeds are expected to double by 2021. In 2016, global average fixed broadband reached speeds as high as 27.5 Mbit/s but are expected to reach 53 Mbit/s by 2021. Between the fourth quarter of 2016 and the first quarter of 2017, average fixed broadband speeds globally equated to 7.2 Mbit/s. South Korea was at the top of the list in terms of broadband speeds.
