Since taking the air in 1985, KFYI has been affiliated with Mutual, CBS, NBC, Fox and ABC. During much of the late 1980s -1990s, CBS was the prime affiliation and KFYI usually aired the top of the hour newscast and used many CBS-fed reports and soundbites. KTAR grabbed CBS for a while and basically buried the top of the hour newscast. KFYI then turned to NBC and eventually ABC-E before getting CBS back. ABC-E newscasts were not as premium as KTAR's ABC-I casts. But when NBC turned to crapola.... they had to find someone, so ABC -E was it. They have more recently been affiliated with Fox, but apparently have CBS as a secondary affiliation. A lot of this also has to do with obtaining sports rights. Back in the day, CBS carried the baseball playoffs and World Series and KFYI ran them, even when those games aired in the afternoon. Much has changed since then. But KFYI may have CBS now because XTRA needs them for some rights package. Just a guess, though.
