The channel began to slowly revamp its programming lineup, acquiring additional recent and older television series and adding marathon-style blocks of acquired series on weekend mornings. A few shows were also dropped from the WGN America schedule (such as longtime staples "U.S. Farm Report" and "Soul Train"), primarily due to the Tribune Company dissolving its television production and distribution unit, Tribune Entertainment. The network's on-screen logo bug was revised In late July 2008, to feature the eye-and-profile element of the logo morphing into the "WGN America" text; the eye-and-profile element remained part of the general logo in all other uses until January 2009, when it was deemphasized in favor of using the channel's wordmark text as the primary logo. In June 2008, Zell and Tribune co-Chief Executive Officer at the time, Randy Michaels, disclosed to the media during a nationwide tour promoting the Tribune properties that the company was interested in producing a late night talk show hosted by comedian Jay Leno, following the end of his initial run as host of NBC's "The Tonight Show" that year, intending to use the Tribune television stations as a major distribution arm and WGN America as a national broadcaster of the show. However, in December 2008, NBC reached a deal with Leno for him to host a new prime time talk show to fill the 10:00 p.m. Eastern Time slot on Monday through Friday evenings. (Low national viewership and concerns about its effects on late local newscasts prompted NBC to cancel "The Jay Leno Show" in February 2010, leading to the network's controversial decision to reinstate Leno as host of "The Tonight Show" one month later, after initial plans to move him to a separate "Tonight" lead-in led to the resignation of his replacement on that program, Conan O'Brien, and O'Brien's subsequent launch of a new late-night talk show on TBS.)
