(各ASPの特長は、順次、日本語に翻訳して行きますー石川)
Commission Junction
世界最大規模のASP, ValueClickに買収される。 東京進出の際、筆者が一時関与したことがあった。
Probably the most popular affiliate network, Commission Junction also has its share of critics. Finding and joining an appropriate affiliate program is easy. CJ also makes things easy for affiliates by consolidating all payouts into one check. It displays EPC (which to CJ rather oddly means "earnings per 100 clicks", not earnings per click). CJ is owned by ValueClick.

Be Free
ValueClickに買収され、サイトは消滅している。歴史に残るASPなので記録として残しておく。
Another large affiliate network with plenty of programs to search through, including some big brands. Merchants include eBay, Staples, Monster, Gap and Travelocity. Be Free has merged with ValueClick.

LinkShare
三井物産の資本参加を得ている。
LinkShare has more than 600 merchants in its affiliate network. Choose from categories such as books, music, flowers, fashion, computers, etc. You'll find some big name companies here, including Dell, Nordstrom, Target, Disney and American Express.

ClickBank
Offers a huge array of downloadable products, mainly ebooks. Because it is cheap and easy for merchants to join, the quality of the products provided varies enormously, from very good to downright awful. It's a popular place to search for overlooked niches.

Performics
DoubleClick に買収される。
Highly professional site with some well known brands. Performics' clients include: America Online, Blair Corp., Bose, CompUSA, Eddie Bauer, HP Shopping, Kohl's, L.L.Bean, PC Connection, RedEnvelope, Verizon Wireless, and more than 200 others. Performics is owned by DoubleClick.
