Not at all surprising to me. According to this article in Business Week, only 16 percent of Innovations come from large companies. Large established corporations are notoriously conservative and short term focused. Not to mention the corporate culture which emphasizes conformity and bureaucracy.
"We studied sources of innovation in 25 consumer product categories over 50 years. From the 1960s to the 1980s, 64 percent of all major new innovations came from large corporations (more than $1 billion in revenue). During the past two decades, only 16 percent of innovations came from large companies, while 84 percent of them came from startups or small companies" - http://www.businessweek.com/innovate/content/may2011/id20110527_276850.htm
