It appears that the recent price cut and/or the BioShock and Halo 3 buzz is helping Xbox 360. Xbox 360 has recently overcome Wii in Google search popularity. Google has over 80% of the search market share, so it reflects a broad selection of users.
Could this be a turning point for the 360?
Updates:
According to Hitwise, (see alternate sources,) the phrase "Xbox 360" is currently searched for more often than "PS3" or "Wii". The logical assumption would be that the Xbox 360 searches spiked as a result of the Red Ring of Death woes and warranty extension. In reality, however, terms related those subjects, such as "Xbox 360 problems" and "Xbox 360 repairs," do not rank into the list of most popular search phrases containing "Xbox 360."
In July, the ten most popular search phrases containing "Xbox 360" are (in the order of popularity): "xbox 360," "xbox 360 elite," "xbox 360 games," "xbox 360 cheats," "madden nfl 2008 for xbox 360," "xbox 360 price drop," "free xbox 360," "xbox 360 achievements," "ps3 vs xbox 360," "the darkness xbox 360."
