Input: Article: There are technical limitations to archiving a web site, and as a consequence, it is possible for opposing parties in litigation to misuse the results provided by web site archives. This problem can be exacerbated by the practice of submitting screen shots of web pages in complaints, answers, or expert witness reports, when the underlying links are not exposed and therefore, can contain errors. For example, archives such as the Wayback Machine do not fill out forms and therefore, do not include the contents of non-RESTful e-commerce databases in their archives.

Now answer this question: What kind of sites contain information that the Wayback Machine does not record?

Output: e-commerce

Input: Article: The original post-punk movement ended as the bands associated with the movement turned away from its aesthetics, often in favor of more commercial sounds. Many of these groups would continue recording as part of the new pop movement, with entryism becoming a popular concept. In the United States, driven by MTV and modern rock radio stations, a number of post-punk acts had an influence on or became part of the Second British Invasion of "New Music" there. Some shifted to a more commercial new wave sound (such as Gang of Four), while others were fixtures on American college radio and became early examples of alternative rock. Perhaps the most successful band to emerge from post-punk was U2, who combined elements of religious imagery together with political commentary into their often anthemic music.

Now answer this question: What was a driving force behind the revival of the second British Invasion of New Music to America?

Output:
MTV and modern rock radio stations
