News Corp's MySpace said Microsoft Corp and Toyota Motor Corp were among 50 advertisers for its programme to target user groups, as it sought to make money from being the world's most popular social networking website.
MySpace is expanding its advertising-targeting programme to 100 categories from 10 when the system was introduced in July.
The company lets marketers buy advertisements aimed at users interested in music, movies and other topics in a targeted manner.
The website will offer the tools outside the United States next year so advertisers can reach international users.
'The most intriguing part of MySpace's announcement is the quality of the advertisers that are participating,' said Richard Greenfield, an analyst at Pali Capital. 'MySpace's ability to improve the value of its display ads and the click-through rates of its vast number of personal-page ads is very significant financially.'
Another tool, allowing small business owners, music bands and politicians to buy advertisements on MySpace and measure their performance, would start early next year, MySpace said.
