In the passage, the author contends that print media is quickly being crowded out by online media. On the contrary, the speaker directly contradicts this point by claiming that the argument is unconvincing and it should be seen from different perspectives.
To begin with, the passage says that the news found on the internet is both fast and up-to-date. For example, once a sporting event finished, within a few minutes, a complete recap and analysis of the game is typically available on the Internet. When it comes to this perspective, the speaker strongly disagrees with it. To be more specific, the speaker says that information is not always good. Sometime online information is not accurate.
Another point the author stresses is that online news is diversified, which means people can read whatever they want from whatever they want. For instance, the author says that a person who enjoys entertainment can find hundreds of sites covering that. On the other hand, this is challenged by the lecturer's assertion. In other words, the lecturer provides pop-up and AD examples to argue the points made in reading passage.
Finally, the reading passage suggests that online media can also provide news from around the world. The lecturer, however, refutes this point by claiming that most people do not care about other country's issues for example Japan.
In conclusion, I have summarized the point made in the lecturer, explaining how the lecturer cast doubt on the points made in the reading.
