G4 or G.IV may refer to:
G4 (also known as G4tv) was an American digital cable and satellite television channel that was owned by G4 Media, a joint venture between the NBCUniversal Cable division of NBCUniversal and Dish Network. The channel was geared primarily toward young male adult viewers and originally focused on the world of video games, before transitioning to a more general entertainment format. G4 was headquartered in Los Angeles.
In late 2012, G4's studio programming ceased in preparation for its relaunch as Esquire Network on September 23, 2013, as part of a licensing deal with Hearst Corporation, owner of Esquire magazine. However, on September 9, 2013, NBCUniversal announced that Esquire Network would instead replace sister channel, Style, leaving G4 "as is for the foreseeable future, though it's highly unlikely the company will invest in more original programming". In August 2013, it was reported that approximately 61,217,000 American households (53.61% of households with television) were receiving G4.
According to a statement by some of the remaining providers carrying the network, G4 would end all operations on November 30, 2014. Programming ceased at 11:59 PM ET on December 31, 2014.
G4 are a four-piece British vocal troupe who first came to prominence when they finished second in Series 1 of The X Factor in 2004, and are known for their operatic delivery of modern pop songs. Originally a barbershop quartet, the members met at the Guildhall School of Music and Drama, from which the name G4, standing for "Guildhall 4", derives.
In 2007 the band disbanded, citing disagreements among the members, but reunited in 2014 to celebrate their ten-year anniversary with a number of concerts nationwide, leading to a new album for Christmas 2015.
The group currently consist of tenors Jonathan Ansell and Ben Thapa, baritone Mike Christie, and Nick Ashby, with the latter replacing former bass singer Matt Stiff in 2014.

It has sold 611,000 copies as of December 2012.
The album features a cover of Queen's " Bohemian Rhapsody".
