Affiliate programs
Adbrite
Adbrite is one of the largest ad networks on the internet. Currently they serve text ads, banner ads, full page ads, InVideo (ads inside videos), inline Ads and BritePic (ads inside images). One of the most distinguishable and notable features in Adbrite is that advertisers can buy ads on sites they choose instead of the having them displayed on various unknown sites through the publisher network.
Adsense
Adsense is the most widely used affiliate program on the internet today. Website owners can sign to Adsense and display text, image and, video advertisements on their sites. Revenue is generated on either a per-click (CPC) or per-thousand-impressions (CPM) basis. Adsense is especially popular because in many languages it is the only affiliate program available.

AuctionAds
AuctionAds just like the name suggests is tied to the eBay auction service. After placing the ad code on a site publishers will see various ongoing auctions displayed. According to the AuctionAds site, money is earned when visitors click on an Auction Ad listing and take an action on eBay. These actions are defined as a Winning Bid, a Buy-it-Now or a confirmed user registration.
Azoogle

Azoogle is yet another Affiliate program that serves ads on a CPM/CPA/CPC basis. Many publishers opted to use Azoogle ads instead of the much popular Adsense affiliate program stating that earnings were much superior.
BidVertiser
BidVertiser is yet another eBay affiliate program much like Auction ads. Publishers earn money from every visitor that clicks on an ad.
Blinkx
With Blinkx you can make money every time you share a video on your blog, website or social networking profile. Before you embed a video into you blog or site, simply run the embed code through blinkx AdHoc first to start making money. When you add the embedded video, it will have contextually relevant ads placed near or on it. If your viewers click on these ads you earn 50% of that revenue.
Chitika
Chitika was one of the first product promotion affiliate program on the internet. Currently it has evolved to include many other advertising options like Related Products Unit (RPU), ShopLinc, ShopCloud$, Owna and Linx.

Text-Link-ads
Text-Link-ads just like the name suggest is a link selling service. There are two ways in which a site owner can make money with TLA. The first is by joining the affiliate program in which $25 is earned from referred traffic that results in a new paid client or new publisher. The second is as a Publisher where by text links ads are displayed on the publisher’s site for a monthly fee.
Widgetbucks
Widgetbucks works much like the Chitika affiliate program, the only difference being that money is earned each time a visitor clicks on a WidgetBucks ad, also called pay-per-click. Just like many other affiliate programs you can also earn money by referring people to sign up. The minimum payout is $50 and since everyone registering automatically receives a $25 bonus, it shouldn’t be to long to before the checks start rolling in.
