 Additionally in 2008, concerns regarding the future of The CW led Tribune to begin rebranding its CW affiliates in a way that deemphasized its network affiliation, and another major CW affiliate ownership group, Pappas Telecasting Companies, cited The CW's poor performance as a factor in its Chapter 11 bankruptcy filing.Pappas has since wound down operations, while most of Tribune's CW stations (with the exceptions of WGN-TV and KTLA, the latter of which only includes network references in promos for CW shows) began reincorporating references to their CW affiliation beginning in 2011.The merger of UPN and The WB to form The CW has led to instability of the airings of "WWE SmackDown", which had aired on UPN for its first seven years.
