Microsoft launched a new marketing campaign on Monday aimed at VMware.

VMware kicks off its VMworld in Las Vegas on Monday and Microsoft wants to remind businesses of the benefits of its solutions. The software giant has created a “VMlimited” mini-site that features Tad the VMlimited sales man. With lines like “I’m a virt guy, it’s all I know, it’s all I wanna know” and “he’s the plan that wants to sell you an outdated IT plan, from the back of a van,” Microsoft’s attack is a comic dig at a big competitor.

Microsoft claims that VMware is “stuck in the past” with its cloud offerings. The marketing campaign is designed to highlight the benefits of Microsoft’s products and services says Microsoft’s communications chief Frank Shaw. “We’ve been having some fun and taking a more pointed tone in some of our communications of late,” said Shaw in a blog post on Monday. “You can expect to see us continue to find ways to tell our story, on our own and against our competitors, especially where there is a gap between perception and facts, using ads, tweets, video, infographics, and, we hope, more than a dash of humor.”

Privately, Microsoft also created the “Gmail Man” video recently, poking fun at Google’s Gmail service. The video was designed to be internal only but leaked onto the web late last month. Microsoft aired it at an internal MGX conference on July 20, depicting a “Gmail Man” who pokes his nose in your business. With Microsoft’s promise of further competitor campaigns in the future, expect to see even more humor from the company.
