Online advertising networks are struggling to make ends meet during a tough economy and a slowdown in industry growth. JellyCloud and Adzilla have shut down while AdBrite had to lay off 40% of its staff.
It's a crowded field with over 300 ad networks, many of them designed to target niche markets. Bigger ad networks, such as AOL's Platform-A, are experiencing struggles in niches such as auto, financial, and telecommunications.
