Twitter has launched a "follow" button for websites, which will enable users to get updates without opening a Twitter page.
More than 50 sites have added the button, including Fox News, the Huffington Post, AOL and the sites of Jennifer Lopez and Lady Gaga, said Twitter.

"For publishers and brands, adding the Follow Button to your website and using Twitter to stay connected with your audience is a powerful combination. People who follow your account are much more likely to retweet and engage with your Tweets, and to repeatedly visit your website," said Twitter in a blog post.
Twitter may be seen as playing catch-up with Facebook's content-sharing facility through the introduction of the tool, which has had a "Like" button on websites for some time.
Recent announcements suggest the microblogging site is gearing up to expand its reach, with plans to open a London office and the recent acquisition of third-party application Tweetdeck in a deal rumoured to be worth around $40m (£25m).
