The most intriguing part of Chapter 3 in Levinson's book, New New Media was the issue of Youtube and iTunes. I had never really seen the tension that could exist between the two modes of entertainment. Levinson posits the question that with Apple's iTunes now charging $1.29 per song and Youtube remaining free, will the Youtube ever beat out iTunes? Personally, I don't much tension between the two at all. Granted there is certainly overlap in their uses as you can search and listen to music or watch music videos on Youtube and do the same by purchasing them on iTunes, but they remain different.
Youtube offers so much more than iTunes because it is a medium for everyone and everything. The content is vast and the uses are too but it's not in competition with iTunes. iTunes allows you to sample a song and purchase it to have to yourself. You can put it on your iPod or another device and you now own that track or CD. Youtube however doesn't allow for this, and every time you want to hear a song you have to find it again and scroll through all the bad quality and false videos to find the one you want.
I can see there may be tension between the two, yet I feel like they are too different to compete to the level of one defeating the other. They serve similar purposes sometimes, but in completely different manners.
