onmuteBlue Jeans Network, a video conferencing company founded by a serial entrepreneur who has sold two companies to Cisco, is adding another $25 million to its coffers from NEA, Accel and Norwest Venture Partners. Interestingly enough, quite of bit of that capital will be going toward a marketing campaign meant to woo enterprise customers away from other video conferencing providers. The company's already got a billboard in San Francisco (pictured above) and the goal is to get more companies to switch from pure audio conferencing to video conferencing.
