Multichannel News: Former media analyst Tom Wolzien’s Video Call Center has snagged its first major investor, former Gannet TV station group Tegna. Wolzien, formerly a top media analyst with Sanford Bernstein, patented the Video Call Center, which enables television shows and networks to conduct live video call-ins much like talk radio programs. With Tegna as a “significant” investor, Wolzien said he will be able to move the product forward. Tegna Media is the largest independent station group of major network affiliates in the top 25 markets in the United States.
