, the online side of the Philadelphia Inquirer and Daily News, is experimenting with selling sponsored tweets. Some standard tweets sent every day, with top stories or weather, end with a "brought to you by..." sponsor line.

Sarah Schmalbach, paid digital content manager for Philadelphia Media Network, told a session at the Newspaper Association of America conference Wednesday morning that "we didn't get any negative feedback" from followers, and that the sponsorship was bundled with a larger print advertising purchase by Xfinity.

Selling advertising in news tweets is unusual, but not unique. The Austin American-Statesman has let advertisers pay for tweets for a couple years now.
