Amazon developing own online advertising software - WSJ

(Reuters) - Amazon Inc is planning to develop its own software for placing advertisements online, The Wall Street Journal reported, citing people with knowledge of the matter.

While the in-house platform is initially planned to replace ads supplied by Google Inc on Amazon's own website, the new system could challenge Google and Microsoft Corp's advertising business in the future, the newspaper cited the people as saying.

Amazon's system would resemble Google's AdWords, and is planned to make it easier for marketers to reach the company's users, the newspaper reported the people as saying.

The retailer is also building a tool that would help advertising agencies buy in bulk for thousands of advertisers, the Journal said, citing the people.

Amazon is known as a sleeping giant in the ad industry because it has rich consumer data but has been tentative about using it for a lot of advertising.

The company already has an advertising service it employs chiefly on its own website.

Amazon did not immediately respond to requests for comment.
