FORTUNE -- The report issued Thursday by Chitika Insights calls it "the power of free" -- a reference to the price Apple (AAPL) charged Mac users to upgrade to Mavericks, the latest version its flagship operating system.
Sampling its ad network last week -- five months after Mavericks' release -- Chitika found that 40% of its clients' page views were coming from Macs running Mavericks. That's six percentage points better than Mountain Lion ($19.99) reached on the same ad network after nearly 14 months.
It may be a record for a computer OS. Nine months after Windows 8 came out, it still hadn't achieved 5% penetration (see here).
But 40% pales compared with the upgrade rates on Apple's smartphones and tablets, where after six months, iOS 7 users were generating more than 80% of Chitika's iOS Web traffic in the U.S. and Canada.
"That disparity," Chitika suggests, "is likely at least partially a function of the nature of the desktop marketplace, where computers are typically kept for a longer period of time as compared to mobile devices, and hence may not necessarily be upgrade eligible. Additionally, a larger and much wider range of users in terms of economics, age and other factors regularly browse using desktops and laptops as opposed to smartphones and tablets, which have user bases skewed more tech-savvy as a whole. Finally, unlike on iOS, where users receive a direct prompt to upgrade to the latest OS version, Mac desktop and laptop users were not actively solicited to update to Mavericks."
A Web ad network's analysis of 2013 see shifts in momentum in the smartphone wars.
FORTUNE -- Apple (AAPL) and Samsung are both expected to launch new flagship smartphones in 2014. To get some baseline numbers in advance, the folks at the Chitika ad network have done a fresh analysis of iPhone and Galaxy usage in 2013.
Their report, issued Friday morning, is based on Apple and Samsung mobile ad impressions in MOREPhilip Elmer-DeWitt - Mar 21, 2014 9:40 AM ET
Today's chart: iPad vs. Android tablets vs. Microsoft Surface, hour by hour
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 MOREPhilip Elmer-DeWitt - Feb 12, 2014 9:45 AM ET
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)

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
