<P> Under the current contracts, the regional Sunday games (1 p.m. "early" and 4 p.m. "late" games Eastern time) are split into AFC and NFC "packages". Each package is held by a single network; as of 2016, CBS holds the AFC package, and Fox holds the NFC package . These packages consist of Sunday afternoon games during each week of the regular season, a single game for each network on Thanksgiving, wild card games, divisional playoff games and the respective conference championship game for each network . </P> <P> These games are classified as "A", "B", or "C" games . "A" games are usually the primary game for each network, and if the network has a doubleheader, is almost exclusively the 1: 00 ET slot . "B" games are typically the primary 4: 25 ET 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 . </P> <P> Market size and team success plays a huge factor in determining the level of games . For example, Green Bay has a city population of 205,000, 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 .) </P> <P> 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 . The current package allows both CBS and Fox access to every stadium / market in the league for at least two games per season (unless an interconference game is chosen as a prime time national game). </P>
