Climbing home broadband access is fuelling the amount of content users who are posting online, such as blog or videos, a new study has found.

The number of US residents with broadband access at home jumped 40 per cent to 84 million between March 2005 and March 2006, double the growth rate of the previous 12-month period, according to the study "Home Broadband Adoption 2006" by the Pew Internet & American Life Project.

This broadband adoption growth in homes is having a direct impact on the amount of content users are posting online. While 35 per cent of all Internet users have posted content online, 42 per cent of home broadband users have done so. Among home users who have posted content online, 73 per cent have a broadband connection.

"Having a fast, always-on internet connection at home is associated with users' posting content to the internet and thereby shaping the environment of cyberspace," reads the study, authored by Johh Horrigan, the organisation's associate director for research.

User contributions are behind some of today's hottest internet services, such as video-sharing sites like YouTube and social networks such as MySpace.

Even search engines are taking advantage of contributions from users. For example, Yahoo has built a search engine called Yahoo Answers whose index is made up of explanations users post to answer each other's questions.

Search engines have also started to leverage services that let users save and categorise links to sites and share these links with others, a phenomenon known as social bookmarking and tagging. Yahoo last year acquired, while most major search engines, including Google Inc and, provide similar services, which they say improves the relevance of their search results.
