Around these parts when we talk about the dynamism and explosive growth of the apps economy, we note that this is an industry that didn’t even exist four years ago. Which means that the last time the Republicans and Democrats gathered for their nominating conventions, very few people were carrying smartphones loaded with these newfangled things called apps.

And look at us now. Convention-goers and –watchers at the Republican National Convention this week are using an AT&T-developed app—Tampa 2012—to keep track of the schedule (which I’m sure they appreciate, given how the schedule has changed due to Isaac), plus find places to eat and drink, find taxis, go shopping, watch the weather (another unexpected bonus), and play in a convention scavenger hunt with QR codes. Those who aren’t in Tampa can watch live streams of the convention and plug-in to social media.

At next week’s Democratic National Convention, there will be a similar app built by AT&T that contains Charlotte-specific information. And Microsoft built an app for the Democrats that helps to streamline convention voting via kiosks on the convention floor. (MS is the DNC’s “official innovation provider,” and also made software contributions to several Charlotte-based non-profits.)
