crawls is the answer to attract viewers’ attention. In addition, that viewers will ultimately be accustomed to the “web-page” like television screen is a firm belief.According to Lang’s (2000) Limited Capacity Model, however, human beings possess a very limited ability to digest information. Dysfunctional memory is likely to occur if message overloads. Related research in this field is scarce and does not deal directly with number of news crawls and content relevancy on information processing. Therefore, this thesis addresses these gaps by investigating the impact of two factors, that is, number of news crawls and content relevancy between news crawls and main news, on viewers’ news information processing (attention and recall in particular). Data was collected based on a computer-based experiment in a university campus with a total of 145 participants. Results showed that relevance between news crawl content and main news content has significant impact on viewers’ attention and recall of news information. Unrelated contents lead to better attention and recall than related contents. More news crawls does not necessarily lead to poorer recall of news information.
