a leader in measuring the digital world, today announced the U.S. Beta release

"We are excited to introduce our Beta version of Media Metrix Multi-Platform,
the next generation in digital audience measurement offering a unified
360-degree view of digital consumer behavior across platforms and content
types," said Jeff Hackett, executive vice president of comScore. "With
smartphones and tablets accounting for a rapidly expanding share of digital
media consumption, comScore recognized the need to evolve our industry-leading
audience measurement product to better represent this new paradigm. By
developing proprietary methods to account for multi-platform audience overlap,
we have designed a truly unique and innovative solution."

Media Metrix Multi-Platform is expected to remain in Beta over the next
several months as the product undergoes a thorough data review and validation
with comScore clients. All publicly reported data included in this initial
report are illustrative and should not be interpreted as official comScore
rankings.

A New View of the Digital World Multi-platform digital audience measurement
has significant implications for how the digital world is seen and understood.
"As an active investor in mobile and web businesses, I have been dying for an
accurate consolidated view of web, mobile web, iOS, and Android audience data.
comScore has delivered exactly what I've been seeking for the U.S. audience
and I am looking forward to seeing them tackle the global audience next," said
Fred Wilson, Managing Partner of Union Square Ventures.

The most notable change from traditional Media Metrix rankings are the overall
audience increases for media properties with a measurable mobile presence; in
some cases, these increases are substantial. Specifically, the Media Metrix
Multi Platform view shows 10 properties reaching 100 million unique visitors
compared to six in a non-multi-platform view, 28 properties reaching 50
million (vs. 19), 77 properties reaching 25 million (vs. 51), 223 reaching 10
million (vs. 171) and 410 reaching 5 million (vs. 334)

Another visible way of reflecting this change is through the ranking of the
top media properties. Properties that are particularly mobile-centric, or at
least have a strong mobile extension of their brands, may realize strong
increases in total audience size and rankings under Media Metrix
Multi-Platform reporting.

Below is a comparison of the top 30 media properties in September 2012
according to the new Media Metrix Multi-Platform Beta rankings compared to the
existing Media Metrix ranking of top web properties. These properties reached
an average incremental audience of 26 percent compared to their desktop
computer-only audience. Other key findings include:

  *Google Sites ranked #1 was the only property to surpass 100 million unique
    visitors across both desktop and mobile channels.
  *Facebook moved up one spot to #3 in the multi-platform rankings, and
    ranked as the top property in terms of total engagement in the mobile
    channel.
  *Amazon, eBay and Walmart each reached at least 20 percent more visitors
    across platforms than via desktop alone.
  *The most mobile-centric property in the ranking, Pandora, had an
    incremental reach of 164 percent and captured the #23 ranking, a full 38
    positions higher than in the standard Media Metrix ranking.
  *Twitter reached an incremental mobile audience of 54 percent, second only
    to Pandora on this list.
  *ESPN had the second biggest jump in the rankings, ascending 4 positions to
    #19, with an incremental mobile audience of 36 percent.

Methodology & Metrics comScore's multi-platform measurement relies on its
proprietary Unified Digital Measurement™ (UDM) methodology, which combines
panel and census-based approaches, to deliver best-in-class estimates of
digital audiences and consumption. In order to provide accurate unduplicated
audience size estimates across digital platforms, comScore developed a
proprietary method that leverages its census web site network to understand
audience overlap across different media channels – the first offering of its
kind to utilize such an approach.

This unified representation of disparate media channels also requires a
modified view of certain standard reporting metrics. While "unique
visitor"-based metrics remain central to Media Metrix Multi-Platform, measures
of engagement such as page views must be reconsidered. This means that
duration-based metrics (i.e. minutes) become the preferred engagement metrics
because they are consistent across media; however, comScore is also
introducing the new "views" metric to account for content-specific
engagements, such as the web-based page view, video view or app start.

Tag Your Digital Content Today! Media Metrix Multi-Platform Beta is available
to U.S. clients immediately, and anticipated for introduction to the UK market
in early 2013. Other international markets will follow thereafter. Publishers,
brands, and media companies who want to ensure that all their digital
platforms and audiences are fully reflected in Media Metrix® Multi-Platform
are strongly encouraged to begin tagging their digital assets with comScore
today at the comScore Direct website .

Many web sites are already familiar with the process from tagging their
traditional web content using comScore's UDM census tag. The comScore tag has
recently been updated to enable advanced measurement of sites and apps in a
fixed web or mobile environment, inclusive of both iOS and Android platforms.
With an increasing amount of media consumption shifting to smartphones and
tablets, now is the time to make sure that all of your digital assets are
accounted for:

  *Traditional web pages
  *Mobile-optimized web pages
  *Mobile apps
  *Tablet apps
  *Video content

If you have any questions about implementing these additional tags, please
feel free to reach out to your comScore account representative.
