After blocking ads that don’t meet Coalition for Better Ads’ recommendations, Google announced that it would block ads that consume too many computing resources. This will apply to ads that consume more than 4 megabytes of network data and those that occupy the browser’s main computing process for more than 60 seconds total or for 15 seconds of any 30-second period. Google will begin experimenting with the technology in coming months and plans to build it into Chrome in August.
