In 1977, Knight Ridder entered broadcasting with the acquisition of Poole Broadcasting, which consisted of WJRT-TV in Flint, Michigan , WTEN in Albany, New York and its satellite WCDC in Adams, Massachusetts , and WPRI-TV in Providence, Rhode Island . Immediately after the acquisition of these stations was finalized, Knight Ridder cut a corporate affiliation deal with ABC , switching then- CBS affiliates WTEN/WCDC and WPRI (the latter of which eventually rejoined CBS) to ABC (WJRT was already affiliated with ABC when the affiliation deal was made). Knight Ridder would acquire several television stations in medium-sized markets during the 1980s, including three stations owned by The Detroit News which the Gannett Company (which purchased the newspaper in 1986) could not keep due to Federal Communications Commission regulations on media cross-ownership and/or television duopolies then in effect. (Interestingly, none of Knight Ridder's later acquisitions changed their network affiliations under Knight Ridder ownership; for example, then-NBC affiliate WALA-TV in Mobile, Alabama remained an NBC affiliate when it was owned by Knight Ridder and would switch to Fox several years after Knight Ridder sold the station.) In early 1989, Knight Ridder announced its exit from broadcasting, selling all of its stations to separate buyers; the sales were finalized in the summer and early fall of that year.
