 DuMont aspired to grow beyond its three stations , applying for new television station licenses in Cincinnati and Cleveland in 1947 . This would give the network five owned @-@ and @-@ operated stations ( O & Os ) , the maximum allowed by the FCC at the time . However , DuMont was hampered by Paramount 's two stations , KTLA ( channel 5 ) in Los Angeles and WBKB ( channel 4 , now WBBM @-@ TV on channel 2 ) in Chicago – the descendants of the two experimental stations that rankled DuMont in 1940 . Although these stations never carried DuMont programming ( with the exception of KTLA for one year from 1947 to 1948 ) , and in fact competed against DuMont 's affiliates in those cities , the FCC ruled that Paramount essentially controlled DuMont , which effectively placed the network at the five @-@ station cap . Paramount 's exertion of influence over the network 's management and the power of its voting stock brought the FCC to its conclusion . Thus , DuMont was unable to open additional stations as long as Paramount owned stations or owned a portion of DuMont . Paramount refused to sell .
