Twitter has for the first time in its history run television commercials during the 2012 Pocono 400 Nascar race in the US.
The seven 15-second advertisements were a part of efforts to broaden its appeal in mainstream America.
They each highlighted a different way Twitter can be used to follow events, the Telegraph reports.
According to the report, all the advertisements pointed viewers to twitter.com/#nascar, where a host of tweets and other material about the race was gathered to make it easier to follow.
Commentators said the campaign was meant to demonstrate to novice users how hashtags work and encourage them to view the website as a destination rather than just a source of interesting links, and to show marketers the Twitter’s potential for promoting brands.
Twitter, however, did not itself explain the motivation behind its first television advertising.
