I got the following email from Google AdSense.
Subject: You're selected: Invitation to join the AdSense inFeed ads beta
InFeed ads are designed to be served in your editorial feeds (for example, a list of articles or news) or listings (a list of products or services). The ads match the look and feel of your content and are highly customizable, giving your readers a better, less disruptive experience. They still know it’s an ad, but it looks great.
The new ads is just showed on smartphone? like List view Matched content?
After I installed the InFeed ads (text only type) on the top page of wanichan.com - between the introduction and Website List
Not bad, huh?
