Apparently following the lead of Apple and Google, Amazon has announced that it will take a smaller revenue cut from apps developed by teams earning less than $1 million annually from their apps on the Amazon Appstore.

The new program from Amazon, called the Amazon Appstore Small Business Accelerator Program, launches in Q4 of this year, and it will reduce the cut Amazon takes from app revenue, which was previously 30 percent.

(Developers making over $1 million annually will continue to pay the original rate.) For some, it's a slightly worse deal than Apple's or Google's, and for others, it's better.

As with Apple's program—but not Google's—the lower rate applies to developers only if they made $1 million or less in total (in this case, the numbers assessed are those from the previous year).

In contrast, Google always takes a smaller cut of the first million in a given year and then applies the bigger cut to revenues after $1 million without changing the amount it took from the first million.
