Hands-On Mobile has secured the worldwide rights to create a mobile phone version of the game to be released later in 2008. A version of the game has been rated by the ESRB for Microsoft Windows computers, though Activision has not officially confirmed this version. A PC version of Guitar Hero World Tour was confirmed by Intel on February 27, 2009 and displayed at CeBIT on March 3–8, 2009 in Hannover, Germany. "World Tour" is available in several bundle packages, as well as the stand-alone game. In addition to a game bundle that includes a wireless guitar for each platform, the game can be bought in one of two bundles that include the guitar, drums, and microphone controller. The second bundle, only available through RedOctane's store, also includes a T-shirt, keychain, and a recharging kit. Players in the United Kingdom who pre-order the full band bundle also received a second guitar controller for bass players. The bass guitar is the Les Paul guitar, the same model as bundled with "Guitar Hero III: Legends of Rock". During the Christmas season of 2008, Some retailers, such as Target, sold in-store a dual guitar bundle which included two identical wireless Les Paul styled guitars from previous game versions and did not include the new guitar with the tapping area. Activision created a series of television advertisements directed by Brett Ratner based on the famous scene from "Risky Business" where Tom Cruise dances to Bob Seger's "Old Time Rock and Roll" in a shirt and underwear, each featuring a different set of celebrities lip synching to the lyrics while using the new instrument controllers. The first ad included athletes Kobe Bryant, Tony Hawk, Alex Rodriguez, and Michael Phelps. Another ad spot featured model Heidi Klum; two versions of Klum's ad exist, one a "director's cut" where she is wearing less clothing. A subsequent commercial featuring model Marisa Miller was banned from airing as too racy. A YouTube viral video entitled "Bike Hero" showed what appeared to be a teenager riding a bike along a route marked with symbols similar in appearance to the in-game note tracks with LED lights on the handlebars blinking in time to the notes to the song "Prisoner of Society" by The Living End. The video was later determined to be the work of a viral marketing company Droga5 in cooperation with Activision to promote the "Guitar Hero" games. The viral advertisement was considered a success, with about 3.5 million views since its release.
