ActivteWeave, the parent company of BlogRovR, has been acquired by BuzzLogic, an online advertising software provider. BlogRovR CEO Marc Meyer and CTO Jean Sini will be joining BuzzLogic as part of the deal, with Sini also becoming the combined company’s CTO.

As you may recall from our previous coverage, BlogRovR is a browser plug-in that shows you related content from a blogs you subscribe to as you surf the Web. For example, if you subscribe to Mashable in BlogRovR, you might see one of our posts about Facebook while you're browsing the social network and have the plug-in turned on.

BlogRovR actually found itself in a mini-controversy here at Mashable last year, as we investigated the impact that the service's default feeds were having on FeedBurner stats for top blogs. Nonetheless, the company’s add-on went on to be installed more than 180,000 times prior to this evening's acquisition announcement.

Meanwhile, the acquiring company was not one I was immediately familiar with, but upon a demo of BuzzLogic’s system, I can see how BlogRovR might fit into their plans. BuzzLogic offers what they like to call an “influence targeting” ad network, meaning that advertising messages are designed to reach specific influencers (generally speaking: bloggers) and their audiences in different genres. For example, if BuzzLogic determines (through linking patterns, author credibility, amongst other characteristics) that I am the pre-eminent expert that blogs about virtual worlds, they may align ads for customers trying to reach virtual world users with my posts.

Since BlogRovR monitors more than 200,000 blogs to provide its content recommendations to users, it’s pretty easy to see where it fits in with BuzzLogic’s plans: providing deeper analysis of who the influencers are in different categories, which in turn should yield better results on ads and put more money in everyone’s pockets.

ActiveWeave was funded by Esther Dyson and Eric Di Benedetto, amongst others. Terms of the acquisition are not being disclosed.
