becoming news director, Nnamdi helped produce The Daily Drum, a local news program. Evening Exchange (1985–2011) Nnamdi left WHUR in 1985 to join Howard television station WHMM (later WHUT) as host of Evening Exchange, a public affairs show. Nnamdi hosted Evening Exchange until 2011. On June 13, 1990, Evening Exchange received its highest viewership numbers when Washington mayor Marion Barry announced on the show that he would not seek a fourth term. Public Interest and The Kojo Nnamdi Show (1998–present) On August 31, 1998, Nnamdi became host of Public Interest on Washington public radio station WAMU, a show renamed from The Derek McGinty Show. In January of that year, previous host Derek McGinty left WAMU for CBS News. A two-hour program, one hour focused on local issues and was broadcast exclusively on WAMU, and the other discussed national topics and was distributed by National Public Radio (NPR) to around 40 stations. On September 30, 2002, Public Interest was renamed The Kojo Nnamdi Show and dropped national distribution. On Fridays, Nnamdi hosts The Politics Hour, which covers topics related to political issues and events in the Washington, D.C. metropolitan area, including surrounding Maryland and Virginia regions. Before May 2008, the show was titled The D.C. Politics Hour and focused solely on the D.C.-area political scene. The show was renamed The Politics Hour in May 2008, after WAMU fired resident political analyst and Washington Examiner columnist Jonetta Rose Barras over a salary dispute. The show then featured guest analysts until the long-term hiring of WRC-TV political reporter Tom Sherwood in February 2009. Barras joined the program after the late Mark Plotkin left in April 2002 to set up shop at all-news station WTOP, where he hosted The Politics Program. Originally called The Politics Hour, the name of Plotkin's show was changed after WAMU threatened a lawsuit. Nonetheless, Plotkin said in a 2006 online chat that he and Nnamdi remain friendly and regularly have dinner together. Every Tuesday the first half of the show consists of a segment called Tech Tuesday that attempts to keep listeners current on various computer/computing and technology issues. For a number of years, the first Tuesday of the month featured "The Computer Guys," John Gilroy and Tom Pivovar. Pivovar left the program in early 2006 in a contract dispute and has been since replaced with a rotation of recurring expert guests, most of whom are employed at either
