Over the coming decades, the Chronicle would see massive growth alongside that of San Francisco, weathering the 1880 assassination of Charles de Young in the Chronicle offices. In 1890, the company built a 10-story building at Kearny and Market streets which was the tallest building in the western United States at the time as well as the first to use steel framing. This building would be superseded by the final company headquarters (still used by the Chronicle), built in 1924 at Fifth and Mission Streets.
With the diversification of interests in the 1960s, the corporation owning the Chronicle was spun off into its own unit as Chronicle Publishing to signify a diversifcation of its interests outside of San Francisco. The second century of the company began with the Chronicle entering a Joint Operating Agreement with the rival San Francisco Examiner in which the Chronicle would publish mornings while the Examiner published afternoons.
Further diversification into broadcasting came in 1975 when the sale of KRON-FM to Bonneville International allowed them to purchase the Meredith Corporation's WOWT-TV in Omaha, Nebraska. This was followed in 1979 with the purchase of KAKE-TV in Wichita, Kansas and in 1987 when independently owned KLBY in Colby, Kansas was purchased to increase KAKE's reach.
Outside of the broadcast realm, Chronicle owned cable systems in California, Hawaii, and New Mexico for several years under their Western Communications unit before those systems were sold to Tele-Communications Inc. in 1995. In the early 1990s, Chronicle launched the Bay TV cable network which was operated in conjunction with KRON and was seen on most cable systems in the Bay Area.
With the exception of the Pantagraph and the book imprints, all of the former Chronicle assets have met some degree of criticism, misfortune, or both. Concerns about the Telegram & Gazette being pared down into a "(Boston) Globe West" arose in Worcester while Hearst's purchase of the Chronicle led to the Examiner having to reinvent itself under its new local ownership as it struggled. The television properties became a strain on their new owners as the Chronicle/LIN/Benedek deal pushed Benedek Broadcasting into bankruptcy with most of the company (including the former Chronicle) stations being purchased in 2002 by Gray Television. Young Broadcasting has struggled since purchasing KRON-TV, having sold four stations and pare down operations at KRON to keep afloat due to the heavy debt incurred by the massive purchase of the station.
