Sales of Google and Asustek's Nexus 7 tablet have steadily increased since its launch, and are now near 1 million units per month.
Asustek Chief Financial Officer David Chang told The Wall Street Journal that Nexus 7 sales have grown from a start of about 500,000 units in the first month. In the latest month of sales, the number was "close to 1 million."
The figures suggest that Google's low-priced tablet has been a moderate success in the tablet market, though nowhere near as popular as Apple's iPad. In its last three-month frame, Apple sold 14 million iPads, which was a 26 percent unit increase from the same quarter a year ago.
Total sales or more specific figures for the Nexus 7 have not been revealed by Asustek or Google. Amazon has also been cagey about revealing sales figures for its 7-inch Kindle Fire tablet.
The Nexus 7 and Kindle Fire face stiff competition from Apple's new 7.9-inch iPad mini, which will go on sale this Friday. The iPad mini has a starting price of $329, which places it at a premium over the $199 entry price of the Kindle Fire HD and Nexus 7.
Google refreshed the Nexus 7 this week by doubling the capacity of the $199 model to 16 gigabytes. a 32-gigabyte model is also available for $249. A model with HSPA+ mobile connectivity with 32 gigabytes of memory is also available for $299.
The Nexus 7 debuted earlier this year in July with Google's Android 4.1 Jelly Bean operating system. It has been seen as an attempt by Google to counter the Kindle Fire, which runs a forked version of Android tailored by Amazon to sell products through its online store.
