Batman and Robin. Siskel and Ebert. Great Britain and the United States in World War II. Cookie dough and ice cream. Usually, when two distinct entities join together, they form one opposable force.
Or do they? While there are major success stories to be found when two large tech companies come together, there's a Time Warner-AOL fiasco for every Oracle-Sun combination.

To see how a few mega-mergers are faring so far, CIO.com decided to check in with a few analysts and experts to get an update on the tech titans of today. Some are working, while others seem poised to join the ranks of the bad tech mergers.
Yahoo and Tumblr: Not much has changed
Yahoo acquired Tumblr in May 2013 for $1.1 billion. Since then, Tumblr hasn't changed significantly, with user counts having only risen about .16 percent over the last year, per Compete.com.
IT analyst Charles King says there was some initial concern over how Yahoo would handle adult-oriented content on Tumblr, but the issue has not raised a stir recently. "It's clear Yahoo hopes it can monetize Tumblr as part of its unified advertising strategy," he says.
Facebook and Instagram: Strong growth to fend off competitors
With some high-profile mergers such as Time Warner and AOL, users responded by fleeing to the hills. When Facebook acquired Instagram in 2012 for $715 million, it seemed like no one noticed (though, King wonders why any company would pay $3 per user.) In fact, one report suggests massive growth -- 90 million new Instagram users since the end of 2012.
Consumer analyst Rob Enderle says the story is still unfolding. There are signs that Facebook will be able to monetize Instagram's still strong user base and that the combination will help fend off mobile competitors such as Snapchat. ( Facebook's recent acquisition of WhatsApp may help here, too, though it's much too soon to tell.
