Protesters attend a rally and march demanding Los Angeles Times not be sold to the Koch Brothers, portraits of which are held, May 23, 2013 in Beverly Hills, California. Charles and David Koch are no longer seeking to buy the Times' parent company, Tribune Co.
The Koch brothers are dropping their pursuit of newspapers owned by the Tribune Co. of Chicago.
Koch Industries, run by the billionaire brothers Charles and David, said Friday that it is still interested in the media and is exploring a broad range of opportunities.
Tribune publications include the Chicago Tribune, the Los Angeles Times, the Orlando Sentinel and The Sun, in Baltimore.
Reports first surfaced four months ago of the Koch's interest in Tribune after the company in December announced plans to sell its papers.
