“The combined “sales rate” is a remarkable $665 million per month, but the split now is that music generates only twice the income of apps (i.e. cumulative is a factor of 5 but on a monthly basis the factor is 2). But what should be more impressive is how quickly the app business is ramping. By the slope of the trend lines, it would appear that app income will exceed music income within three years. Therefore, it’s only a matter of time before apps generate as much income (exclusive of advertising) as music.” #trendtaste - × × ×

“Another perspective is the number of downloads per device per month. This shows that the rate of consumption of apps is increasing and is now about 6 apps per device per month. (You have to think of apps not as traditional computer applications or console games where each device has a certain number of expected apps attached, but rather that apps are more like a subscription where there is recurring monthly income). ¶ I don’t have a comparable figure for music because the number of iPods and Macs as target devices is hard to estimate, but I doubt consumption for music on a per device basis is increasing. As a consolation, I can estimate the number of apps or songs per iTunes account. Here the story is consistent.” - × × ×
