A product category-level decline
Facebook says that since the site was founded in 2004, its users have uploaded more than 50 billion photos, making that feature one of its most popular. Flickr, the photo-sharing site, says users add more than three million photos to its inventory every day. Yet Flickr’s data shows that the most popular camera among its 55 million users is a smartphone, Apple’s iPhone 3G. Not a single point-and-shoot makes it into its top five. The remaining spots are occupied by S.L.R.’s from Canon and Nikon.
Cameras began showing up in phones almost a decade ago. For much of that time, image quality was akin to grainy shots of U.F.O.’s or Sasquatch. In the last few years, though, more powerful processors and better sensors have improved image quality to levels many consumers find acceptable.
