This allowed both Fox and CBS affiliates in a team's primary market to carry games from the team during the season. After a Broncos-Vikings game was moved to Fox in 2011 because of Fox having a lack of games as a result of an NFL flexible scheduling policy ("see below"), the NFL permanently instituted a "cross-flex" policy in 2014, allowing Fox games to be moved to CBS and CBS games moved to Fox. The Sunday games are classified as "A", "B", or "C" games. "A" games are usually the primary game for each network (1:00 ET for Eastern and Central time zone or 4:05 ET for Mountain and Pacific time zone games in a single-game week), and if the network has a doubleheader, is typically the 4:25 ET game. "B" games are typically the primary 1:00 ET game when the network has a doubleheader, or the secondary game if the network has a single game. "C" games are only shown in the playing teams markets and in some cases, markets if the game has playoff implications for the local team. Market size and team success plays a huge factor in determining the level of games. For example, Green Bay has a city population of 105,000, one of the smallest for a city with a sports team. But the Packers usually have the "A" or "B" game because of their long history and almost unparalleled success. (The team is actually two markets for the NFL policy; Milwaukee is the other primary market for the team.) The Dallas Cowboys (due to that team's national popularity) and the New England Patriots (due to that team's success since Bill Belichick took over in 2000) have typically been shown in the national doubleheader timeslot in recent years for ratings purposes, despite affiliate requests to show a team that may have more appeal locally; these games are typically decided by the NFL and CBS or Fox, depending on who has the doubleheader that week. In 1970, when the NFL and AFL merged, and home blackouts were put into place for AFC games (some AFL teams had lifted these during its run; as an example, most New York Jets' home games in 1968 and 1969 were telecast on WNBC-TV New York), this assured that all Sunday afternoon away games would be seen on the same network. On occasion, both of a team's home interconference games are played in prime time, depriving the opposite conference's network of any games involving the team. This happened in to the Los Angeles Rams, to the Indianapolis Colts, to the Houston Oilers, to both the Buffalo Bills and San Diego Chargers, and to the Miami Dolphins, to the New England Patriots, to the Baltimore Ravens, to the Atlanta Falcons, to the Arizona Cardinals and to the Las Vegas Raiders.
