Google are leaving the digital world rather confused today with the viral-isation of their latest ad for 'Search with my location', fittingly entitled 'Pizza'.

The excruciatingly irritating 10-minute long video sees the (presently unknown) character cycle through a series of random backdrops, whilst attempting to search for pizza with his voice using the Google iOS app. The baffling absurdity of already finding local results 18 seconds in, before wasting a further 10 minutes of our lives is only exacerbated by the fact he's using an iPhone 4 as opposed to one of Google's heavily pushed Android handsets.
