NetMarketShare today admitted that the apparent mega-drop in XP’s market share was due to changes in its data network.
The market watcher yesterday released figures stating that XP finally started to lose its grip on the operating system market, dropping 6.7% in the month of October. While many sites hailed this as the beginning of the end of for the legacy OS, others – including MicroScope – took the data with a pinch of salt. What is surprising is that the data for October is actually a more accurate reflection of the current market landscape.
NetMarketShare today posted the following explanation for the seismic shift:
“This drop was primarily caused by a major change in the network of sites we have in China. A group of large Chinese publishers with a very large number of visitors per day had audiences heavily skewed towards Windows XP (nearly 100% XP). In researching the nature of the sites, we determined they were not appropriate for our network. We removed those publishers ourselves, which caused the shift since Chinese traffic is weighted higher due to lower coverage. The current data set is more accurate than in the past due to this.”
What this means is that one of the primary data sources being used by the industry as a litmus test for the current market ecosystem has in fact been overhyping XP’s dominance for some time.
NetMarketShare added that it was ‘researching ways to prevent outlying sites from causing this problem in the future’.
