The document discusses the paywall system adopted by The New York Times, which allows up to 20 free articles per month before requiring a subscription fee. As print revenue declined due to the shift to digital, online advertising was not sufficient to replace the lost income. The Times had to decide between a "leaky paywall" that allows some free access or a "bulletproof paywall" with no free access. It was determined that a leaky paywall would be better initially to attract more subscribers and generate website traffic through social media. Both print and online newspapers are needed, as online versions are more convenient for today's mobile lifestyles.
