Another day, another ad technology/data acquisition. Oracle is in a race with Salesforce.com and others to weave together social CRM services and analytics, while Google wants to shore up its already strong position in online display advertising. But it’s going to take more than cobbling together “an operating system for advertising,” whatever that means, to connect the dots across social media, online ads and search, and deliver valuable ad inventory to brand advertisers. You know, the ones that spend billions on TV. There remain plenty of opportunities to do that dot-connecting, however. Even if the landscape is starting to clear out a bit.
