They had good customer base initially. AOL has done so many acquisitions for like Adaptv(video advertising platform), Millenial Media(mobile advertising) etc which were pretty successful. Later ofcourse Yahoo. Failure started coz they platform integration plan didn't work as expected. Lot of talent from the acquisitions left. They still use lot of old tech setup for advertising, web platforms. In summary, they failed in making a single platform from acquisitions they had.
