Apple's suppliers have begun manufacturing new iPad tablets, Bloomberg reported, citing people with knowledge of the matter. Apple has seen growth plummet from 2012, as larger phones became more popular and people delayed replacing their tablets.

Mass production of the iPad with a 9.7-inch screen has already started, and it is likely to be unveiled by the end of current quarter or early next quarter, Bloomberg said, citing two people familiar with the matter.

A new version of the 7.9-inch iPad mini is also entering production and is likely to be available by the end of the year, Bloomberg said.
