Reach the Education and Youth Market.
If your market is education, consider that all universities already offer Internet access to their students and all schools are on the Internet already.
Books, athletic shoes, study courses, youth fashion and anything else that would want to reach these overlapping markets needs to be on the Web.
Even with the coming of the commercial on-line services and their somewhat older populations there will be nothing but growth in the percentage of the under 25 market that will be on-line.
