Several of the participants had not seen any broadcasts and those that had were alerted to them via social media.
Prior to being shown the films via Campaign and Watch Me Think, one viewer from Cornwall said: "I hadn't seen any party election broadcast anywhere – internet or the television."
Another viewer from Lewes said: "It all just tends to come mainly through the internet, like social media."
The Green Party video, by Creature of London, stood out the most, but many viewers felt that they did not learn anything about the party's policies from the broadcast.
The satirical election broadcast is based on a 70s television show, showing a family playing a boardgame that urges voters to "change the game".
One steadfast Labour voter from Daventry said: "It was immature, it wasn't serious."
Another viewer from the City of Chester said: "The Green one stood out the most because it was the board game thing but it was annoying because it didn't have any policies in it."
The feedback to all the ads was mixed; some participants said that the broadcasts may have swayed them to rethink their vote, while others said they had done nothing to make them change their mind ahead of Thursday's election.
