Peterborough, N.H.--ActivMedia Research, an Internet-commerce research firm, said last week that the data in its annual electronic study support the contention that the Web is more a transactional vehicle than advertising medium. Of business-to-business sites, 61.5% surveyed earned revenue from products and services, according to ActivMedia. "As might be expected, only 9% of consumer and b-to-b Web sites offer paid ad space or links, preferring to keep customers focused on their products," explained Harry Wolhandler, VP-research for ActivMedia. In contrast, 54% of media/portal sites surveyed said they generated revenue from advertisers. Additionally, 51% of media/portal sites said they also earned revenue from selling products and services.
