New submitter cvdwl writes: A New York Times (mildly paywalled) article and associated analysis discuss the consumer cost of mobile ads, assuming a US$0.01/MB data plan. The article provides one of the only estimates I've seen of the the real cost in time and money (and time is money) of mobile advertising. Ethics of ad-blockers aside, this highlights the hidden costs of data-heavy (often lazy and poorly developed) web-design. In a nutshell, the worst sites took 10-30s load 10-20MB, costing $0.15-0.40, over 4G due to a blizzard of video, heavy images, and occasionally just massive scripts. The best sites had high content to ad ratios, typically loading 1-3MB of content and >500kB of advertising.
