A Merrill Lynch e-commerce research report forecasts that businesses on the web will register a 20 percent increase in e-commerce and a 14 percent rise in online travel bookings from the second quarter of 2005, reports Internet News. In contrast, total U.S. commerce and travel spending are expected to increase 6-8 percent and 4-5 percent, respectively. E-Commerce sales and online travel bookings are on track to meet, but not significantly beat, expectations, according to the firm. According to research firm Gartner, one out of three web users is buying less online because of security concerns related to data breaches, identity theft and phishing.
