Online app stores have exploded onto the technology scene over the last half a dozen years. More recently enterprise app stores have become a thing. As a result, millions of people download and install applications onto their mobile devices, laptops and desktop computers every day. Apple’s App Store is the largest and highest profile app store, but it wasn’t the first major online app store when it launched back in 2008. That title belongs to AppExchange, a business app store Salesforce.com launched in 2006.
