In Media? You have a new home. Techmeme launches a new aggregator, Mediagazer.

Gabe Rivera has launched a new property, Mediagazer, as another column in his network of vertical content websites.

Mr. Rivera is of course the man behind Techmeme, a website that everyone in the world of technology is familiar with. An aggregation service, it uses a powerful algorithm to harvest news, and then employs a team of human  editors stitch together the pieces to create the most dynamic collection of news stories, headlines, and discussion in the technology space around current topics.

Less known in tech journalism are Techmeme’s sister sites. The company also operates BallBug (Baseball), WeSmirch (celebrity gossip), memeorandum (politics), and now Mediagazer covering the most important news in the media industry.

Talking to Paid Content‘s Staci Kramer, Techmeme editor McCarthy said that the four-year time difference between the last vertical launch and Mediagazer was due to work perfecting their model: “We spent the last four years evolving and perfecting our aggregation model and finally did the next vertical when we thought it was mature enough.”

The company sells sponsor slots on its verticals, meaning that each site brings in sufficient revenue to handles its curation and maintenance. In that vein, Mediagazer is launching with four sponsors. All but one are new; Seesmic sponsors Mediagazer and Techmeme. The website is very similar to the look and feel of the other verticals in the network.

And of course, Mediagazer does have those new share buttons that were unveiled last week. Techmeme et al know how important they have become, and the new sharing links at the top of each headline story section give readers the ability to link back to that section on the websites simply. Mediagazer will benefit from this functionality from launch.

Will the website succeed? I can safely say that while researching this story, half my time was spent reading content I that came across on Mediagazer. If that is any indication, we have another Techmeme on our hands.
