Q: Question: What does CBS stand ford? Passage:In September 1998, alongside the launch of The WB 100+ Station Group (The WB 100+), WLAJ began operating a cable-only affiliate of The WB which was part of the national service. This was available exclusively on Comcast channel 30, had its own logo, and used the "WBL" call sign in a fictional manner. From 2002 until 2006, the internal operations (such as advertising sales) of UPN affiliate WHTV were housed at WLAJ's studios. That station then relocated to the WLNS facility after entering into a joint sales agreement with WLNS' then-owner Young Broadcasting. On January 24, 2006, The WB and UPN announced the networks would merge. The new combined network would be called The CW. The letters represented the first initial of its corporate parents: CBS (the parent company of UPN) and the Warner Bros. unit of Time Warner.
