Twitter on May 31 broadened its reach by letting websites add "Follow" buttons that visitors can click to begin tracking posts at the globally popular microblogging service. Twitter billed the button as "a new way to follow Twitter accounts directly from the websites you visit every day."
The feature was rolled out the same day Web advertising company AdGrok announced it has been bought by San Francisco-based Twitter.
Websites that took part in the Follow button launch included online venues for pop stars Lady Gaga, Justin Bieber and Britney Spears as well as news, sports, and videos.
"More than 50 sites have added the Follow Button as part of today's launch, making it easy for people to discover the Twitter accounts of their favourite reporters, athletes, celebrities, and other personalities," Twitter said.
