The Sony ad, created in-house, sets itself up as an instructional video, only to show the two demonstrators simply swapping a game face-to-face. It follows confusion around announcements from Microsoft, which have been understood by many to prohibit the shared and pre-owned games market.
According to Unruly, the ad was shared 626,081 times across the web this week.
Following Apple's Worldwide Developer Conference (WWDC) earlier this week, a video showed at the event promoting Apple's design credentials has entered the chart in sixth place.

The ad, in which people waiting at a bus stop are secretly photographed and then 'Photoshopped' into animations played on the side of the same bus stop, promotes Adobe's #CreativeDay hashtag.
