becoming available on the service, before being replaced by direct response advertising thereafter. Due to restrictions put in place by the network in January 2012 to encourage live or same-week DVR viewing via traditional and cable on demand methods, Hulu and Fox.com both impose an eight-day delay for most viewers to access the most recent episode of any Fox program, restricting day-after-air streaming of its shows on both services to subscribers of certain pay television providers (such as Dish Network and Verizon FiOS) using an ISP account through agreements made with Fox, along with Hulu's free service with advertisements on Yahoo! Stream; however, Hulu offers newer episodes of Fox programs the day after their original broadcast to paid subscribers requiring only a user-determined login. In March 2020, Fox began to stream the full schedule of all of their owned Fox Television Stations through FoxNow. The following month, Fox acquired the ad-supported streaming service Tubi. The service primarily offers content and channels licensed from third-party studios, but later began to add episodes of Fox Entertainment original series (such as The Masked Singer) a week after their television premiere. Fox HD Fox began broadcasting its programming in 720p high definition on September 12, 2004, with that day's slate of NFC football games during week one of the 2004 NFL season. Until March 14, 2016, the network did not display an on-screen logo graphic on the bottom-right corner of the screen, outside a ten-second sweep of a "Fox HD" promotional logo (which until the end of 2010, also featured a sponsor tag for DirecTV); instead a trigger in Fox's program delivery system at each station displayed the logo bug of an owned-and-operated or affiliate station in the right-hand corner of the 16:9 screen frame, which disappeared during commercial breaks (the station logo bug would still be triggered even if Fox programming was pre-empted locally due to breaking news, severe weather coverage or special programming, though some stations, such as WGGB-DT2 in Springfield, Massachusetts, did not display a logo or substitute only the "FOX" logo alone). However, network or affiliate bugs are not displayed during Fox Sports programming. During some high-profile or live programs such as American Idol and So You Think You Can Dance, however, Fox forwent the affiliate's logo and displayed its network logo instead, mainly for promotional consideration due to fair use of clips from each series by other media outlets
