A majority of visitors to websites of monthly magazines in the US are accessing the content online rather than paying for a copy, according to a survey by Nielsen//NetRatings and MRI.
An average of 83% of visitors to the sites of the 23 high circulation monthlies that were featured in the study did not read the magazine offline.
In a similar move to rival web measurement firm Nielsen//NetRatings, comScore has decided to make change to the way it measures web audiences.
comScore will now divide internet audiences into heavy, medium and light users, in an attempt to help advertisers better segment their audiences.
Web traffic measurement agency Nielsen/NetRatings will reportedly scrap the "page views" metric in response to the growing challenge posed by dynamic websites.
Ajax websites and web-based videos mean content can be loaded with no web page reloading, so the firm will begin instead reporting the length of time users spend at audited sites.
The Interactive Advertising Bureau (IAB) has announced it has reached an agreement with both comScore and Nielsen/NetRatings over auditing of their measurement techniques.
Last month, the IAB challenged both metrics firms to throw open their methods to inspection by independent auditors and expressed concern about the use of panels to measure web audiences.
New stats from Nielsen//NetRatings show that young women are spending more time online, with the 18-34 age group accounting for 18% of the UK internet population.
According to these stats, the 18-34 age group is the largest online, accounting for 34% of UK internet users.
The Interactive Advertising Bureau (IAB) has again raised concerns about the measurement of web audiences and has called for major research groups to open up their systems to an independent audit.
IAB president and CEO Randall Rothenberg has written an open letter to the CEOs of comScore and Nielsen//NetRatings, challenging both firms to throw their methods open to scrutiny.
A new study by Nielsen/NetRatings examines the top UK websites using three different metrics - page impressions, visitors, and time spent. It concludes that the page view is becoming less relevant, a mantra we're hearing increasingly often.
The report argues that the growth of Web 2.0 sites, and the different ways that users are interacting with social media means that advertisers are looking beyond the page impression as a way to measure user behaviour.
Online spending rose by 42% on ‘Black Friday' - the day after Thanksgiving in the US - according to figures from analysis group comScore.
Total US online spending for the first 24 days of November reached $8.31bn, a 23% increase over the same period in 2005. Black Friday saw a 42% increase on 2005's figures.
