Interpreting Data Reveals Biases

Before you go gung-ho about a certain brand gaining market share, or losing it, think about this:

“Individual data slices aren’t as revealing as multiple slices. For example, using BCN’s yearly numbers (Disclaimer: BCN changed the way they counted in 2014, going to a straight brand share instead of top 20 products determining share), we can see that Panasonic slid from nearly a 40% market share in Japan in 2010 to about 13% in 2014. That’s significant. Especially when you realize that such sales themselves peaked in the middle of that timeframe. Sony started strong in mirrorless in Japan, lost steam, then regained it. Nikon started modestly and has lost momentum. Canon started even more modestly and gained a bit of momentum. ”
