Web content management (WCM) software may generate more than US$1 billion in revenue for its vendors, up from $890 million during the recession-laden 2009, analyst firm Gartner stated in a report, "Magic Quadrant for Web Content Management,"
It appears the big analyst firms continue to give little attention to Drupal's healthy penetration into the enterprise because "Drupal" software doesn't generate enough revenue for a single entity.
What enterprise marketing and sales tools do you need to help evangelize Drupal into these organizations that are going to pay $1B for WCM software? Keep in mind that the $1 Billion is usually focused on software, subscription, and maintenance. Systems integration, hosting, and customization revenue is usually many multiples of the software revenue.
