720p refers to a progressive HDTV signal with 720 horizontal lines and an aspect ratio (AR) of 16:9 (1.78:1). All major high definition (HD) TV broadcasting standards include a 720p format which has a resolution of 1280×720, however there are other formats, including HDV and AVCHD for camcorders, which utilize 720p images with the standard HDTV resolution. The number 720 stands for the 720 horizontal scan lines of image display resolution (also known as 720 pixels of vertical resolution), while the letter p stands for progressive scan (i.e. non-interlaced). When broadcast at 60 frames per second, 720p features the highest temporal (motion) resolution possible under the ATSC and DVB standards.

720i (720 lines interlaced) is an erroneous term found in numerous sources and publications. Typically, it is a typographical error in which the author is referring to the 720p HDTV format. However, in some cases it is incorrectly presented as an actual alternative format to 720p. In fact, no proposed or existing broadcast standard permits 720 interlaced lines in a video frame at any frame rate. 720i can also refer to technology in which only half the lines are shown each scan.

Mario Barwuah Balotelli (Italian pronunciation: [ˈmaːrjo baloˈtɛlli]; born 12 August 1990) is an Italian footballer of Ghanaian descent who plays as a striker for Manchester City and the Italian national team. He started his professional football career at Lumezzane and played for the first team twice before having an unsuccessful trial at FC Barcelona, and subsequently joining Internazionale in 2007. Inter manager Roberto Mancini brought Balotelli into the first team, but when Mancini left, Balotelli's disciplinary record fell away. He had a strained relationship with new head coach José Mourinho and was suspended from Inter's first team in January 2009 after a number of disciplinary problems.

His problems deepened in March 2010 when he came under heavy criticism by Inter fans after he appeared on the Italian TV show Striscia la notizia, wearing an A.C. Milan jersey. This damaged the prospect of him having a long career at Inter, but he did make several appearances after that. With doubts over his career at Inter, former coach Roberto Mancini at Manchester City gave Balotelli a fresh chance at a new club. He joined Manchester City in August 2010, where his performances and off-field activities have continued to be controversial and enigmatic. Balotelli earned his first cap for the Italian national team on 10 August 2010, in a friendly match against the Côte d'Ivoire thus making him the first black player to play for the Italian national football team.

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
