I got a tip from a reader that mobile social and file sharing site (MOSOSO), Zedge.net was being acquired by multinational telecom conglomerate IDT. I can't confirm that this is accurate so take it as an unfounded rumor. I'd never heard of Zedge or IDT so I did a little digging. Mashable was apparently also tipped and has a post up.
Update: The IDT - Zedge deal is real. Announcement here. I also heard from Fabio Pezzotti at Mobango and he says that Mobango has 1.2 million users. Fabio also mentioned that Zedge changed their domain from Zedge.no to Zedge.com this year which explains their sudden growth spike on the Alexa charts. Finally, Mobango is not advertising that heavily in the US or anywhere - only $50/day on AdSense again according to Fabio.. I'm sure I've seen those ads though - I think it was on HowardForums.
What really surprised me was how big Zedge is, claiming 3.5 million users. Last week I wrote about another MoSoSo, Mobango which doesn't disclose it's user numbers but which has a huge amount of shared content - 200,000 files. Well, Zedge tops that with 400,000 files. It's impossible to get traffic data for mobile sites but we can look at traffic metrics for their associated PC sites. Both Mobango and Zedge require users to interact with their PC sites to register, update their profiles and push data to the mobile. I know Alexa data is considered suspect, but I think it's actually OK for comparing similar sites. Here's a graph from Alexa comparing Zedge with Mobango, MoSoSo pioneer TagTag and another site I'd never heard but which is the apparent market leader in the mobile social networking space, Mobile9.
The graph shows that Mobango passed TagTag this year. But look at the blue line, that's Zedge which has come out of nowhere in one year to challenge Mobile9's leadership. I obviously need to review both Zedge and Mobile9 very soon! I don't think most US mobile users have even heard of either Mobile9 or Zedge but they appear to be the largest mobile social networks in the world. (Mobango has been advetising on US phonefan sites so I think it has some name recognition in the states). If the rumor of an acquisition by IDT is true that may change. IDT is a US based, 2 billion annual revenue company whose products include VOIP pioneer Net2Phone and the Hispanic targeted MVNO, TúYo wireless. IDT recently sold their Entertainment division and a Russian telecom so they should have some cash available for an acquisition. It certainly makes sense that a fast growing mobile social and content sharing network like Zedge would be attractive takeover target. We shall see - but it looks like MoSoSo may be poised for a takeoff worldwide and in the US.
