Born in southeast Cleveland, Mileti put himself through college, graduating from Bowling Green State University (BGSU) in 1953.
He became involved in sports after serving as chairman of the Bowling Green alumni association and organizing a BGSU game at the Cleveland Arena.
[3] In late 1972, Mileti formed Ohio Communications with veteran radio executive Tom Embrescia, which acquired WKYC AM/1100 and FM/105.7 from NBC, renaming them "3WE" WWWE-AM and "M105" WWWM-FM.
Mileti then moved the radio play-by-play rights for the Indians and Cavaliers, as well as pioneering sports talk host Pete Franklin's Sportsline, to WWWE.
Already the most powerful AM station in Cleveland, with a 50,000 watt clear channel signal, WWWE quickly turned into a sports radio powerhouse.
However, his plans were undone when two major partners in his Indians syndicate, Steve O'Neill and Gabe Paul, joined George Steinbrenner's bid to buy the New York Yankees.
