This was the second edition of the show to air in the same year. Originally, only one summer edition was due to air, but the 2007–2008 Writers Guild of America strike prompted CBS to air an additional season, Big Brother 9, from February to April during the regular television season and Big Brother 10 for the summer of 2008.
Big Brother 10 was noted as a "back to basics" season by both CBS and the production team. As part of the back to basics format, live audiences returned for the Thursday eviction shows (something not featured since season 1), there were thirteen HouseGuests, and they were once again complete strangers (after several seasons of having some HouseGuests already know each other). Plus, similar to Big Brother 2 and Big Brother 3, the first HOH was based on HouseGuests' first impressions of each other.
Big Brother 10 lasted just 71 days, nearly a week and a half shorter than most seasons, making this the shortest season of the American series of Big Brother. This also marked the last time that the season number or year of airing would be mentioned in the broadcast and in the logo; subsequent seasons were simply referred to as Big Brother, with the logo omitting the season number in favor of an animation of a shutting door.
- Temporary America's Player: On week 4, Dan was given the opportunity to become America's Player for that week only. He accepted and succeeded in all 3 of his tasks.

Before even speaking to one another, the houseguests had to cast their vote for whom they wanted to be the first HOH of the summer. After receiving 4 votes, Jerry MacDonald was crowned HOH. That night, Jessie Godderz and Renny Martyn engaged in an argument after Jessie claimed he couldn't sleep due to Renny being loud. Despite Renny's numerous apologies, Jessie claimed that she did not apologize to him. The folllowing day, Jerry chose to nominate Renny and Jessie for eviction, claiming he wanted to avoid conflict in the house. Jessie won the POV competition. The vast majority of the house later went to Jerry and asked him to nominate Brian Hart for eviction, as he had been making deals with numerous houseguests thus far. Jessie used the Veto on himself, and Jerry nominated his former ally Brian. Brian was evicted in a nine to one vote.
Following Brian's eviction, the houseguests competed in the "Majority Rules" Head of Household competition, where Jessie was the winner. Jessie nominated Dan Gheesling and Steven Daigle due to their close friendship with Brian. On Day 11, HouseGuests competed in the "License to Veto" Power of Veto competition, where Michelle Costa was the winner. Michelle chose not to use the Power of Veto. Steven was evicted from the house in a unanimous vote.
Following Steven's eviction, houseguests competed in the "Alien Abduction" HOH competition. Keesha Smith won the competition and was crowned HOH. She decided to nominate Angie Swindell and Jessie Godderz for eviction. At the Veto competition, Keesha was victorious and won the POV. She chose to leave her nominations intact. Angie was evicted unanimously.
At the first endurance competition of the season, April Dowling won HOH. In the hope of evicting Memphis Garrett, she decided to nominate Memphis alongside Jessie Godderz. At the POV competition, Libra Thompson was the winner, but chose to take a Hawaiian vacation instead, and gave Jerry MacDonald, the runner-up, the POV for the week. He chose to leave nominations intact. Following numerous arguments in the house, several houseguests turned on Jessie, and in turn, April and Ollie, and decided to go against April's wishes and evict Jessie. Jessie was evicted by a vote of 4 to 3.
At the end of the competition, Michelle Costa was the last standing and won HOH. After Michelle won the competition, she swore that her HOH win was "for Jessie". At the nomination ceremony, Michelle revealed that she had decided to nominate Libra Thompson and Keesha Smith. Jerry won the "Cry Me a Veto" POV competition, and chose to leave nominations the same. Libra was evicted unanimously.
Following Libra's eviction, Renny Martyn won the "Diary Room Confessionals" HOH competition. Before Renny made her nominations, the rest of her alliances tried to convince her to nominate both Bryan Ollie and April Dowling together. At the nomination ceremony, Renny decided not to follow her alliance's wishes and nominated Jerry MacDonald alongside April. Dan Gheesling won the POV and decided not to use it. April was evicted by a four to one vote.
After another endurance HOH competition, Dan Gheesling was crowned HOH. During the competition, Dan had made a deal with Bryan Ollie; the deal was that if Ollie let Dan win the competition - he and a houseguest of his choice would be safe from eviction, he would be able to choose one of the nominees and he could choose the replacement nominee if the Veto was used. Ollie asked for Michelle Costa to be safe and for Memphis Garrett to be nominated. Dan originally stuck to the deal and nominated Memphis alongside Jerry MacDonald. However, before the Veto competition, Dan told his alliance that he was not going to stay loyal to the deal. Memphis won the POV competition and removed himself from the block. Dan chose Michelle as the replacement nominee. Michelle was evicted by a vote of 3 to 1.
The houseguests learned that it would be a Fast Forward night, and a second houseguest would be evicted. Keesha Smith won the "Big Brother Headlines" competition, minutes later, and chose to nominate Jerry MacDonald and Bryan Ollie for eviction. Dan Gheesling later won the "Veto In a Haystack" POV competition, in which houseguests had to dig through hay to find two Veto pieces. He chose to leave Keesha's nominations the same. Minutes later, Ollie was evicted in a unanimous vote.
The HOH competition was not held until later that night due to the double eviction episode. At the competition, it seemed as if it was Jerry MacDonald versus the rest of the house. However, Jerry managed to win the competition and was crowned HOH. The following day, Jerry nominated Dan Gheesling and Keesha Smith for eviction. Memphis Garrett completed the Veto competition in the fastest time and won the POV. Staying loyal to The Renegades alliance, Memphis decided to use the Veto on Dan. Renny was the only possible replacement nominee. Renny was evicted unanimously.
After the HOH competition, Dan Gheesling had the most correct answers and became the new HOH. The Renegades came up with a plan to make it look as if they were no longer working together. Following through with the plan, Dan nominated Memphis Garrett and Jerry MacDonald for eviction. The plan was successful as Memphis won the POV and removed himself from the block. Dan and Memphis both decided to turn on their fellow ally Keesha Smith, as they thought she would be more difficult to beat in the final HOH competition than Jerry. Memphis cast the sole vote to evict and chose Keesha.
The final HOH competition is played out in three challenges, to give the remaining houseguests a fair shot at securing a place in the final two. During the first endurance HOH competition, Dan Gheesling won the challenge. Days later, Memphis Garrett beat Jerry MacDonald in a memory recognition challenge, meaning Jerry was nominated. At the live HOH part 3 competition, Dan beat Memphis in a personality guessing quiz, claiming the final HOH. He then chose to evict Jerry.
