Asus Chief Financial Officer David Chang told the Wall Street Journal this week that his company is selling nearly one million Nexus 7 tablets every month. On Tuesday, the manufacturer announced a dramatic increase in Q3 tablet shipments, which jumped by nearly 200 percent over the second quarter, though both Asus and Google have been reluctant to disclose precise sales figures for the Nexus 7.

"At the beginning, it was, for instance, 500K units a month, then maybe 600, 700K. This latest month, it was close to one million," Chang said. These figures signal an encouraging trend for Asus and Google, though they're still far below iPad sales, which reached 14 million last quarter.

Chang's comments come just a day after Google announced the new Nexus 7 (32GB + Mobile) and Nexus 10 tablets, alongside the Nexus 4 smartphone.
