The package was officially announced on October 17, 2006. Under the terms of the arrangement, Fox retained its rights to the network's regular-season package, which would now begin in April, and would remain the exclusive home of the All-Star Game and World Series. Fox's postseason coverage beyond the World Series is limited to one League Championship Series per year (the American League Championship Series in odd numbered years and National League Championship Series in even numbered years), which alternates every year with TBS (which took over exclusive rights to the Division Series from ESPN) airing the other LCS.
