Twitter Inc had hired an advertising executive from Google Inc to be head of its retail division. The move was after the company had ramped up hiring and works to expand its business ahead of its most anticipated public debut.

Google's media and entertainment advertising director JJ Hirschle would now be responsible in selling advertising products to retail companies in Twitter Inc. This was according to Twitter representative Will Stickney. Hirschle would start his post in the social media platform on October 28.

Twitter's hiring came as the social network platform build up its advertising business by reaching out to retailers. The company had been hiring quickly to boost its workforce and expand its businesses. Twitter said in a filing this week that it had added 300 employees in the third quarter. This totaled the number of workers in the social media company to 2300, said a report from Bloomberg.
