with the respective launches of the MountainWest Sports Network (now defunct) and Big Ten Network in 2006 and 2007 and the later launches of the Pac-12 Network and ESPN's SEC Network and ACC Network, athletic conferences have acquired rights for all of their member university's sports programs for their cable channels, restricting their use from PBS member stations, even those associated with their own universities. From 1976 to 1989, KQED produced a series of Bundesliga matches under the banner Soccer Made in Germany, with Toby Charles announcing. PBS also carried tennis events, as well as Ivy League football. Notable football commentators included Upton Bell, Marty Glickman, Bob Casciola, Brian Dowling, Sean McDonough and Jack Corrigan. Other sports programs included interview series such as The Way It Was and The Sporting Life. Governance The board of directors is responsible for governing and setting policy for PBS, consisting of 27 members: 14 professional directors (station managers), 12 general directors (outside directors), and the PBS president. All PBS Board members serve three-year terms, without pay. PBS member stations elect the 14 professional directors; the board elects the 12 general directors and appoints the PBS president and CEO; and the entire board elects its officers. Member stations , PBS maintains current memberships with 354 television stations encompassing 50 states, the District of Columbia and four U.S. possessions; as such, it is the only television broadcaster in the United States—commercial or non-commercial—which has station partners licensed in every U.S. state (by comparison, none of the five major commercial broadcast networks has affiliates in certain states where PBS has members, most notably New Jersey). The service has an estimated national reach of 93.74% of all households in the United States (or 292,926,047 Americans with at least one television set). PBS stations are commonly operated by nonprofit organizations, state agencies, local authorities (such as municipal boards of education), or universities in their city of license; this is similar (albeit more centralized in states where a licensee owns multiple stations rebroadcasting the main PBS member) to the early model of commercial broadcasting in the U.S., in which network-affiliated stations were initially owned by companies that owned few to no other television stations elsewhere in the country. In some U.S. states, a group of PBS stations throughout the entire state may be organized into a single regional "subnetwork" (such as Alabama Public Television and Arkansas PBS); in this model,
