With the start of the baseball season, fans also flocked to MLB.com, driving up traffic 50% to 9.8 million visitors. Bankrate.com and its affiliated sites enjoyed a 46% gain to 5 million through the addition of InsureMe.com in early March.
Among video sites, Break Media grabbed the spotlight as its audience increased 35% to 7.9 million.
Separate data from Nielsen Online showed that Google remained the top site overall, with almost 120 million visitors last month--trailed mostly closely by Yahoo, at 114.5 million.
