The latest stations joining MyNetworkTV’s affiliate roster include Meredith Broadcasting Group’s UPN affiliate KPDX-TV in Portland, Ore. (the 23rd-largest market in the country), and WB affiliate KSMO-TV in Kansas City, Mo. (market No. 31); Roberts Broadcasting-owned UPN-affiliated WRBU-TV in St. Louis (No. 21); Venture Technologies Group-owned UPN affiliate WNYA-TV in Albany, N.Y.

MyNetworkTV is cleared in 45 percent of the United States.

Fox Television Stations CEO Jack Abernethy said in the announcement that “with an entrepreneurial spirit reflective of MyNetworkTV, [the stations] each bring powerful attributes to the network, and we are looking forward to working with them.”

Meredith Broadcasting President Paul Karpowicz said in the announcement, “In a very competitive landscape, we think the MyNetworkTV model offers a great opportunity from a ratings and revenue perspective.”

Gregg Filandrinos, executive VP and chief operating officer of Roberts Broadcasting, said in the announcement, “This network represents the most effective and productive model to be a national broadcast network affiliate without losing control of your localism.”
