FORTUNE -- The folks at the Chitika ad network set out last month to test whether Microsoft's (MSFT) Surface -- heavily promoted as the tablet best suited for doing real work -- is actually being used more in work settings than Apple's (AAPL) iPad or all those tablets that run Google's (GOOG) Android.
To find out, they analyzed tens of millions of North American ad impressions between Jan. 20 and Feb. 2 and produced the pair of charts attached above and below.
Among their findings:
"Despite the usage statistics presumably indicating some success for Microsoft in this area," the report concludes, "the company has a long way to go before challenging Apple or Google in terms of raw usage volume during working hours."
CAVEAT: These charts are for North America only.
Two charts illustrate a key difference between the two leading mobile operating systems.
FORTUNE -- The chart at right, taken from the Wikipedia entry for Android version history, illustrates the problem app developers call Android fragmentation -- the splintering of Google's (GOOG) installed base into incompatible fragments. Applications that run on one combination of hardware and software don't necessarily run on others.
Wikipedia doesn't offer a similar chart for Apple (AAPL) iOS, and the graphic MOREPhilip Elmer-DeWitt - Dec 13, 2013 7:26 AM ET
The iPad's share of tablet Web traffic edged up in May. The others are going nowhere.
FORTUNE -- Based on Web usage, the tablet market in North America still looks like Apple and the 13 dwarfs.
The chart above was posted Monday by Chitika, a mobile ad networks that runs about 4 billion spots per month across 300,000 websites in the U.S. and Canada and -- shades of the N.S.A. -- collects MOREPhilip Elmer-DeWitt - Jun 24, 2013 12:07 PM ET
iPhone and iPad users sleep at night. Android users, not so much.
FORTUNE -- Here's a curious finding from the folks at Chitika, an online advertising agency that runs mobile ads on some 300,000 websites in the U.S. and Canada.
For a report released Wednesday, the company tracked roughly 300 million ad impressions hour-by-hour during the first week of May and graphed the results according to which mobile platform the visitor was MOREPhilip Elmer-DeWitt - Jun 12, 2013 11:51 AM ET
The iPad's usage share in North America rose in March for the first time since December.
FORTUNE -- Despite increased competition from tablets running Google (GOOG) Android, the presence of Apple's (AAPL) iPad in the Chitika online ad network rose in March to 81.9%, up from 80.5% in February.
According to the report Chitika issued Thursday, the rest of the tablets are all distant also-rans.
In the same one-month time period, it saw the presence of MOREPhilip Elmer-DeWitt - Apr 18, 2013 2:57 PM ET
According to Chitika, the iPad has recovered somewhat from its post-Christmas dip
FORTUNE -- There was some consternation among Apple (AAPL) investors in early January when the Chitika Ad Network -- which sells data about the online activities of hundreds of millions of users to its advertising clients -- published a version of the chart at right. It showed the iPad's share of North American tablet Web traffic dropping 7.14% in MOREPhilip Elmer-DeWitt - Feb 6, 2013 8:29 AM ET
Early reports that its reception was "not-so-spectacular" seem to have been off the mark
Trip Chowdhry of Global Equities Research stuck his neck out Sunday and pronounced sales of the new iPad "somewhat light." Relying on the number of hits on Chitika's ad network-- always a risk, in our experience -- he went so far as to suggest three reasons that the new iPad's launch was such a disappointment: (I quote)
Lack of MOREPhilip Elmer-DeWitt - Mar 19, 2012 12:42 PM ET
Wyoming and West Virginia, at 4.19% apiece, have the lowest concentration of Apple computers
Apple's (AAPL) share of the U.S. PC market is still shy of 10%, according Gartner's first quarter 2011 report, but some parts of the country are more Mac friendly than others.
Drawing on research gathered between June 2 and 8 by Chitika's ad network, which serves more than than 70 million impressions per day, MacDailyNews reports that San MOREPhilip Elmer-DeWitt - Jun 28, 2011 6:07 AM ET
5,000 iPad apps created, 12 million app downloads, 1.5 million ebooks bought at the iBookstore
In a press release issued Monday morning, Apple (AAPL) announced what several analysts had already surmised: that it has sold more than 1 million iPads.
It passed the seven-figure milestone on Friday, 28 days after the device's introduction on April 3 and the same day the iPad 3G went on sale. It's not clear from Apple's release MOREPhilip Elmer-DeWitt - May 3, 2010 10:27 AM ET
Also, 63% own Macs, 8.5% iPhones, 2.89% Linux boxes and 1.3% Android phones
Dan Ruby at Chitika Labs -- the folks who run the much revised live iPad tracker (907,000 as of Friday afternoon) -- sent along the bar chart at right.
It shows, based on a survey of nearly 75,000 early iPad adopters, some of the non-Apple (AAPL) devices they own.
To Ruby's surprise, more than half of those surveyed have PCs MOREPhilip Elmer-DeWitt - Apr 16, 2010 2:51 PM ET
