Today, Broadpoint AmTech released a study exploring how web portals like Yahoo, AOL and MSN are faring in the current web environment. Tracking over the past few months shows that Yahoo is still a key brand and the YouTube has really emerged with its front page ads, while MSN has the largest amount of direct-response ads and AOL is called the most adventurous.

Telecom and media advertisers were the largest ad players with 27 percent of home page buys, and financial services followed at 14 percent. Rich media remains very popular, with nearly 93 percent of home page ads implementing it; 57 percent are using standard sizes (usually in Flash) and an increasing number (28 percent) are using expandable or oversized ads.
