YouTube launched its TV streaming services Wednesday. According to GfK MRI’s Survey of the American Consumer, millennials aged 18 to 34 account for 43 percent of the “cordless” population, ones who have never had cable, satellite or fiber optic TV service and those who have “cut the cord.”

If numbers are anything to go by, the amount of time users spend watching TV has gradually been declining and more and more people are switching to online TV streaming services. YouTube TV is aimed at catering this rising number of users at just $35 a month. Subscribers will get access to four major broadcast networks and a bundle of over 40 cable channels.
