I don't think anything is going to become obsolete any time soon, it takes generations for things like that to happen. 58 percent of Americans still own a VCR, which is 13 points more than people who own an MP3 player, and 19 points more than people who use Netflix/Hulu.So according to consumer research (I guess?) cable, land lines, newspapers, CDs/DVDs, camcorders, and books are going to be obsolete in the next 3-20 years; cable because of Netflix, land lines because of cell phones, camcorders because of "still cameras", and books because of Kindle and eReaders.
