Online editions of Tribune's newspapers were developed starting in 1995, with the "Chicago Tribune"s digital edition launching in 1996. Also in 1996, Tribune (holding a 20% interest) created a joint venture with American Online (which held an 80% interest) called Digital City, Inc. to set up a series of Digital City websites to provide interactive local news and information services. By 1997, Tribune Publishing had only four daily newspapers remaining in its portfolio: the "Chicago Tribune", the "Fort Lauderdale Sun-Sentinel", the "Orlando Sentinel" and the "Daily Press". Tribune also set up its Tribune Ventures division to acquire stakes in newer media businesses. During the middle of that year, Tribune Ventures purchased interests in companies such as AOL (owning 4%), electronic payment specialist CheckFree Corporation (owning 5%), search engine company Excite, Inc. (owning 7%), Mercury Mail, Inc. (owning 13%), Open Market, Inc. (owning 6%), and Peapod LP (owning 13%). Also that year, the "Orlando Sentinel" and Time Warner Cable joined together to create the Orlando-based local cable news channel, Central Florida News 13. Tribune also purchased a 31% stake in the Food Network.
