John Lawson, former president of the Association of Public Television Stations, is leaving ION Media Networks to relaunch his consulting firm. He ran Convergence Services Inc. from 1993 to 2001, when he accepted the head position at APTS (Current, March 26, 2001). He oversaw the lobbying org until 2008, then departed for ION (Current, Feb. 19, 2008). Convergence Services will provide consulting for the digital media industry “at the intersection of business, technology and policy,” Lawson said in a statement he distributed to pubcasting execs yesterday. He will focus on building mobile DTV networks and services, development of public media and deployment of next generation emergency alert systems. The company may seek financing for its own ventures, the statement added. APTS is currently searching for a president in the wake of Larry Sidman’s departure (Current, March 14). Convergence Services Inc. officially reopens on April 19.
