Via Sue Marek of Fierce Wireless comes a staggering number from Verizon:

Video accounts for 50 percent of Verizon Wireless’  network traffic today and by 2017 the carrier estimates video will make up two-thirds of all traffic over the network. Speaking at the National Association of Broadcasters conference here yesterday, Verizon Communications CEO Lowell McAdam said that the company’s investment in its LTE network is what is making the delivery of that video possible. “With 3G you have video clips but there is buffering. With 4G you can stream video,” he said.

50% of wireless traffic and counting. Wow.
