The Times newspaper now charges readers to access its online content.
From now on, access to The Times and Sunday Times website will cost £1 ($2.20) per day or £2 per week via a subscription.
News International, which owns the papers, announced plans to impose charges earlier this year in response to falling advertising income.
Currently the Financial Times and The Wall Street Journal are the only major newspapers with similar paywalls.
The BBC reports falling readership numbers and advertising revenues have put significant pressure on newspapers in recent years. Devising the best way to make money from content is seen as a major challenge for the industry.
