"American sports factored in prominently for the top gaining categories
and properties in March," said Jack Flanagan, executive vice president of
comScore Media Metrix. "The NCAA tournament drove substantial traffic to
online gambling sites during the month, while the start of spring training
made MLB.com one of the top gaining properties. Both events also contributed
to ESPN.com's surge in the top properties rankings."
Top-Gaining Sites for March
Yellow Book Network secured the top-gaining site position for the month,
with a 54-percent gain to 13.5 million visitors due, at least in part, to a
new partnership with addresses.com. Baseball spring training and fantasy team
drafts prompted a flood of earnest fans to MLB.com, which jumped 50 percent to
9.8 million visitors. Bankrate.com Sites witnessed a 46-percent increase to 5
million visitors with the addition of the InsureMe.com entity in March.
Radio Sites See Surge in Visitation
Radio sites experienced a sharp increase in traffic in March with the
category growing 27 percent to 61.8 million visitors, making it the
top-gaining category for the month. AOL Music led the category with 21.9
million visitors (up 5 percent), followed by Yahoo! Music with nearly 20.8
million visitors (up 4 percent) and Clear Channel Online with 11 million
visitors (up 2 percent). Other significant increases were experienced by
Pandora.com (up 9 percent), Citadel Broadcasting Corporation (up 11 percent),
and Disney Music (up 17 percent).
Online Gambling Traffic Propelled by March Madness
The NCAA basketball tournament, also known as "March Madness," attracted a
flurry of online bettors, prompting a 14-percent gain to the online gambling
category. Sportingbet PLC increased 35 percent to 975,000 visitors,
UPICKEM.net jumped 174 percent to 396,000 visitors and SportsBetting.com rose
114 percent to 145,000 visitors.
Walgreen Co. Leads Retail - Health Care Category
Retail - Health Care sites experienced a 12-percent increase in March to
26.3 million visitors, as Walgreen Co. led the category with 5.4 million
visitors (up 10 percent). Drugstore.com, Inc. captured the second position
with 3.7 million visitors, followed by CVS with nearly 3 million visitors.
Top 50 Properties
The top 10 properties maintained their positions from February with Yahoo!
Sites continuing to lead as the top property with 139.5 million visitors,
followed by Google Sites with 137.5 million visitors and Microsoft Sites with
121 million visitors. ESPN jumped 12 spots on the popularity of March Madness
and anticipation of the 2008 Major League Baseball season. Gains were also
experienced by AT&T (up 8 spots to #18 with 31.3 million visitors), Target
Corporation (up 5 spots to #20 with nearly 30 million visitors), and CBS
Corporation (up 6 spots to #24 with 28.6 million visitors).

The top 10 Ad Focus properties also maintained their February rankings
with Platform A, the ad network combining Advertising.com, Tacoda, AOL, and
Quigo, leading the ranking in March, reaching 91 percent of Americans online.

of the 188 million Americans online. Real Cities Network and YuMe Video

respectively.
