other HOH sole power for the rest of the week. There were eight Battle of the Block competitions in season 16 and five in season 17. Battle of the Block did not return after season 18. Battle Back The Battle Back Competition allows an evicted HouseGuest to return into the house and play as if they were never actually evicted. While elements of this competition first appeared in Season 15, it was officially introduced in Season 18 and has appeared in subsequent seasons except Seasons 22-24. The losers in each Battle Back faces permanent eviction, and the winner in the final Battle Back competition won re-entry. A variant of a Battle Back also appear in Season 20 where the recent evicted HouseGuest competed in a single challenge (due to a twist) to determine whether the HouseGuest was allowed re-entry if successful. Another variant also happened on Season 18; dubbed as "Round Trip Ticket", the ticket would allow the HouseGuest who picked it to re-enter the house immediately following eviction (for a certain time); HouseGuests are told not to open the ticket until their eviction, and doing so before the eviction will void the effect. Series overview Controversy and criticism Since its inception, Big Brother has been criticized following reports of "HIB" (Harassment, Intimidation and Bullying), violence in the house, obscene language, breach of integrity, and the physical and mental strain of appearing on the series. Several seasons have also been criticized for racism and discrimination, most notably season 15 and season 21. On September 9, 2018, Chen's husband, Les Moonves, resigned as President of CBS after a second wave of reports of sexual misconduct allegations against him. On September 13, Chen closed out that evening's episode by saying, "From outside the Big Brother house, I'm Julie Chen Moonves. Good night." As Chen had previously never used Moonves professionally, many saw the move as Chen standing in solidarity with her husband. Following her resignation from The Talk on September 18 after eight years as co-host, there was speculation on whether Chen would continue as host of Big Brother. Chen did return to host the following year, and has become increasingly spiritual and religious on and off the program in the wake of such revelations.
