For someone like me, youtube is actually more important than having a tv at home. Its because most of my day is spent in the university, shuttling between job, classes and finishing classes. So by the time I reach home, its generally quite late. So rather than watching tv (and paying for cable), I prefer to watch most of the stuff (music videos, sitcoms, movies, sports matches etc.) in the univ on youtube, during the free time I have.
