<P> One of the main aspects of the series is the live feeds, in which viewers can view inside the house at any time . The live feeds have been a part of the series since its inception, initially being offered as a free service during the first season . From the second season onward, a subscription to the live feeds has been required, with the price ranging each year . The first season's feeds were available on the show's official site, hosted by AOL . From the second season to the fourteenth season, the feeds were available through RealNetworks either as a subscription or as a free addition for Gold members . With the fifteenth season onward, the live feeds have aired on the official CBS website, again requiring a subscription from users . Though advertised as being available at any time, the feeds are shut off during the weekly nomination ceremony, Power of Veto ceremony, and the competitions and evictions for that week; this is to provide suspense for the series . Slanderous statements and singing of copyrighted music are also blocked for legal reasons . </P> <P> CBS is set to be premiering Celebrity Big Brother in the winter of 2018 . It will be the first spin - off to air on the broadcast network, and the second season overall to air in the winter television season . The celebrity edition is expected to air in a concentrated run with fewer episodes . However, this edition will air multiple episodes each week and continue to have live feeds and the After Dark companion show as with the main edition . </P> <P> The Head of Household competition is held at the beginning of each week, and is most often performed on the live eviction episode . Most often, the first Head of Household competition will require HouseGuests to participate either in pairs or in teams . While the fourth, fifth, and eighth seasons had the HouseGuests competing in pairs, the sixth, seventh, eleventh, twelfth, fourteenth, fifteenth, and sixteenth editions all saw HouseGuests competing as part of a group . The live Head of Household competitions are typically question based, and will see HouseGuests eliminated each round . Competitions such as "Majority Rules" have been used numerous times, with the game being played in the fourth, fifth, sixth, eighth, tenth, and twelfth seasons; a variation of the competition was used in the seventh season . Some competitions will attempt to cause drama in the house, such as the "En Garde" Head of Household competition in which the winner of each round selected the next two to face off against one another . This competition was later used in the tenth, eleventh, twelfth, thirteenth, fourteenth, fifteenth, and sixteenth seasons . Various competitions throughout the season will be endurance, requiring HouseGuests to be the last one remaining in the competition . Endurance competitions are often held after game changing announcements, such as when a previously evicted HouseGuest returns . Various endurance competitions may have punished or reward contestants who either fall off first or last . Skill based competitions also appear frequently throughout the season, some of which may last for numerous hours . Skill competitions, such as the thirteenth season's "Big Brother Open", are finished during the live eviction broadcast . The final Head of Household competition of each season features three rounds; the first is endurance, the second is skill, and the final is question based . The record for most Head of Household competitions won in a single season is held by Drew Daniel, Janelle Pierzina, Hayden Moss, Rachel Reilly, Ian Terry, Aaryn Gries, Caleb Reynolds, Vanessa Rousso and Steve Moses in terms of reigns . Frankie Grande won HOH 5 times the sixteenth season, however he was dethroned twice due to the dual HoH twist that was in play during his season, and third reign was rewound due to the rewind button twist . This leaves Frankie with just two full reigns as HoH . Ian Terry has the record for most consecutive Head of Household wins, with four (winning at the Final 9, 7, 5 and 3 rounds). One of the Head of Household's duties is to nominate 2 people for eviction . Victoria from the sixteenth season holds the record for most times being nominated with nine . </P> <P> The Power of Veto is a power first introduced in Big Brother 3 . During it's first season, it did not allow a nominated HouseGuest to use it on themselves . The final Power of Veto that season was the Golden Power of Veto, and allowed a nominated HouseGuest to remove themself from the block . Following this, the Golden Power of Veto was used in all subsequent seasons . The Diamond Power of Veto, used in Big Brother 12 allowed one HouseGuest to remove themselves from the block, as well as choose the replacement nominee only moments before the live eviction. Power of Veto competitions differ drastically from the Head of Household competition, with PoV competitions being more skill based in nature . Competitions such as the "Pop Goes the Veto!" competition, which required HouseGuest to find letter tiles and spell the longest word, have been used in numerous consecutive seasons . Competitions such as the "Big Brother Boardwalk" competition see HouseGuests attempting to guess how much of an item there is; this is one of various competitions that do not require HouseGuests to compete in a physical based competition . The "How Bad Do You Want It?" Power of Veto competition, first introduced in the seventh season, saw HouseGuests taking punishments in exchange for advancing in the competition . Variations of this competition have been used in numerous subsequent seasons . HouseGuests Janelle Pierzina, Daniele Donato & Paul Abrahamian currently hold the record for most Power of Veto wins in a single season, with five wins each . HouseGuests James Zinkand, Frank Eudy, and Shane Meaney all hold the record for most consecutive Power of Veto wins, with three each . </P>
