Sportsvision was a subscription TV service founded by Chicago White Sox owners Jerry Reinsdorf and Eddie Einhorn, and media mogul Fred Eychaner.
The network began in April 1982 as Sportsvision, a joint venture between then-new owner Chicago Bulls and White Sox owner Jerry Reinsdorf, his fellow White Sox co-owner, television sports producer and promoter Eddie Einhorn, and Fred Eychaner, then-owner of local UHF station WPWR (then on Channel 60, now Channel 50).
Eychaner signed on WPWR-TV, with a large percentage of its broadcast schedule dedicated to a new subscription television service called Sportsvision that was part of ONTV, which Eychaner had developed in a deal with Chicago White Sox owners Jerry Reinsdorf and Eddie Einhorn.
