Longtime executive Bill Anderson has resigned after more than two decades as the leader of the CBA, the major umbrella group for Christian retailers. Anderson, 61, abruptly ended his role as president and CEO of CBA, the organization formerly known as the Christian Booksellers Association, in late October, as reported by Christian Retailing in its December 7 issue. Anderson gave no reason for his departure. He became the association’s first full-time convention manager in 1978. At its peak in 1999, the annual summer convention had close to 15,000 in attendance. Since then, the industry has struggled with competition from big-box chains and online retailers.
