Today, I would like to share an interesting concept I have stumbled on. First of all, I am going to give a statiscians warning, correlation does not equal causation. However, let's pretend it does! Take a look at the graph above. Notice anything? Well, simply put, the rise of search for iTunes is anti-correlated with CDs. In essence, more searches for iTunes equal less searches for CDs.
Now, don't go burning down iTunes for the destruction of our plastic relics. Instead, this graph just indicates that the Google users could be described as slowly replacing CD searches with iTunes.
What's really worrisome about this graph is that CD can also mean certificate of deposit. So, either this is indicative of the decline of physical music sales, or else everyone is fleeing interest bearing accounts (which is plausible in today's economy). Just some food for thought.
Also, note that there is a slight bump in all music related searches near the end of the year. Still looks like music is a good gift.
