In broadcasting, a blackout is when certain programming, usually sports, cannot be televised in a certain media market.
The purpose is theoretically to generate more money by obligating certain actions from fans, either by making them buy tickets or watch other games on TV. While financially a logical procedure on the part of those providing the programming, blackouts are frequently unpopular with the affected audience.
Canadian federal elections results are a prominent exception of non-sports-related programming that is subject to blackout. The reason for this is because of the numerous time zones, and since polls close at different times in the country, results from one region may influence voting in the next.
A similar term, known as preemption (or "pre-emption"), often refers to stations blacking out a program for other than regulatory or governmental reasons, such as when a local station preempts a network program for local news (an example of a regular preemption) or a special program (an example of a one-time preemption).
However, in the federal election in 2000, one Paul Charles Bryan published results from Atlantic Canada on the Internet despite being told not to by the authorities. Bryan was charged before the Provincial Court of British Columbia, but fought the charges as unconstitutional under section 2 of the Canadian Charter of Rights and Freedoms, which protects freedom of expression and freedom of association. Bryan's victory before the British Columbia Supreme Court meant that voters in British Columbia and the rest of Canada legally learned of election results in other ridings during the federal election in 2004. However, Bryan lost his case before the British Columbia Court of Appeal. He further appealed to the Supreme Court of Canada, but in a ruling made on March 15, 2007 the Court ruled that Section 329 of the Canada Elections Act is constitutional and justified under section 1 of the Canadian Charter of Rights and Freedoms.
Stephen Harper, who later became prime minister, labelled Elections Canada "jackasses" and tried to raise money for Bryan. The Canadian Broadcasting Corporation also supported Bryan, hoping to "make election night a bigger event that it already is."
Before the 2000 election, Elections Canada moved to reduce the effects of the blackout and the influence of unauthorized knowledge of election results in Western ridings by altering the times that polls close so that polls no longer close at the same local time throughout the country. Polls in Atlantic Canada now close at 9 p.m. Atlantic (9:30 in Newfoundland). Polls from Alberta to Quebec close an hour later (9 p.m. Eastern, 8 p.m. Central and 7 p.m. Mountain) and finally, polls in B.C. close an hour after that (7 p.m. Pacific). Historically, the results of the election are often not decisively known until more than an hour after polls close in Ontario and Quebec, but are usually known within two hours of these polls closing.
Provincial elections are not subject to blackout restrictions - in those provinces that have two time zones the vast majority of the population lives in one time zone or the other. Election laws in these provinces stipulate that all polls are to close at the same time - this time invariably being 8:00 p.m. (or 9:00 p.m. in Ontario beginning with the 2007 provincial election) in the time zone of the majority.
The home team has the option of lifting a blackout for games that sell out. Unlike in the NFL however, the home team is not obligated to lift a blackout in such cases.
The cable network TSN holds the national rights to selected games through the year as well as regional rights to Toronto Maple Leafs games. TSN splits its network during Leafs games so that only Ontario viewers see the game, viewers in other markets see alternate programming. On Wednesdays TSN holds a similar monopoly to the CBC on Saturdays. Rogers Sportsnet holds the regional rights to the other Canadian teams. Like TSN, Rogers splits their network for those games.
In the French language RDS broadcasts all of its Montreal Canadiens games across the full network.
Also, ESPN's blackout zone is larger than that of the superstations.
In the NHL, the policy has changed in recent years. Now, most national cable games are shown throughout the country. Occasionally, the league will grant its cable partner an exclusive window and not schedule any other games involving U.S. teams at that time. For NBC's network coverage in the 2006-2007 season, only games it televised could air during its window, airing different games by region. The coverage was changed in the 2007-2008 season to a Game of the Week format.
In MLB there are no radio blackouts. However, for many years, the radio networks of the two participating ballclubs in the World Series were not allowed to air games. This changed after 1980, fans of the Philadelphia Phillies were angry that they couldn't hear their popular broadcasting team of Harry Kalas and Richie Ashburn call their run to the title. Since then, only the flagship stations of the two participating ballclubs can originate coverage, though their broadcasts are also available on XM Satellite Radio. XM is required to broadcast the home, away, and both English and Spanish national feeds of the World Series. All other network affiliates of the two clubs must carry the feed from MLB's national partner (currently ESPN Radio), and they may not even be able to do so if they compete with an ESPN Radio affiliate in the same market. The two flagships must broadcast ESPN Radio national commercials (though they can run live commercial reads during broadcasts and sell ads during typically extended pre/post-game shows).
Additionally, radio stations (including flagships) may not include MLB games in the live Internet streams of their station programming. Some stations will replace the game with a recorded message explaining why the game cannot be heard on their stream. Others will simply stream the station's regularly scheduled programming that is being preempted by the game.
The NFL blackout is considered to be detrimental to financially struggling teams. For instance, most notably, the Los Angeles Rams were unable to sell-out their home games during their last years in that city, so a blackout further robbed the franchise of potential revenue and alienated remaining fans.
There is also another exception with regard to the Green Bay Packers, as that team has a home market that extends across two television markets, Green Bay and the larger market of Milwaukee to the south; the team had formerly played at least two games a year in that city's County Stadium. However, blackout rules rarely factor in the area, due to the team's routine sellouts going back to 1960, and a season ticket waiting list years long.
Radio rules are similar to that of Major League Baseball. Westwood One has national exclusivity for the Conference Championship games and Super Bowl, although the local flagship stations may broadcast these games (Green Bay/Milwaukee is a unique case where a Milwaukee radio station is the Packers network flagship, but there are also AM/FM flagship stations in Green Bay).
For other games, no station within of an NFL stadium may broadcast a game unless it has an affiliation deal with one of the local teams involved. One instance of the practice of this rule was over Hartford, Connecticut CBS affiliate WFSB trying to air a New England Patriots-New York Giants game for December 29, 2007, which would be carried only on the NFL's cable network NFL Network that at the time was available only on a sports channel package of Comcast Cable in the immediate viewing areas of the Patriots and Giants.
On December 12, 2007, Broadcasting & Cable reported that Senator John Kerry and Rep. Ed Markey, both of the state of Massachusetts and fans of the New England Patriots team, wrote to the NFL as well as Comcast Cable and Time Warner Cable to request that the Patriots-Giants game be aired at least on basic cable in order to reach the highest possible number of television-viewing fans, as at the time the Patriots were undefeated, and Kerry and Markey viewed the game as "potentially historic", according to John Eggerton of B&C. Kerry clarified the next week that he did not intend to interrupt current negotiations between the cable operators and NFL. On December 19, 2007, representative Joe Courtney (D-CT) and other members of the Connecticut Congressional Delegation wrote to NFL commissioner Roger Goodell to try to have the NFL allow wider broadcast access to the game. Consequently, on December 26, the NFL approved the game to be simulcast from NFL Network to both the CBS and NBC networks.
