The graph shows  the up-rise of the  Internet video and the downfall of  live broadcast tv   from 2010 to 2022.  The trend line of the amount of hours  people spend on live TV has  decreased and the amount of hours people spend on  Internet videos has increased over time. Its estimated  that by 2019  the amount of hours spent on  Internet videos  will be same as the traditional Live TV. After 2019 the online stream videos will surpassed the Live TV.  At this rate I think the online stream videos will completely eliminate the live Broadcast TV because nowadays majority live TV content can be watched on online stream however it can’t be done other way around. Online stream  is way more easier and  efficient. It expands peoples’ option to watch content.
