Mitchell Weisburgh summarizes the BMO Capital markets' Equity Research on Education and Training report (aside: I never did like the name switch to BMO. Contrived and artificial.) "There were $200 billion of private investments in the education market in 2000. There was $181 million in 2003. This bounced back to $364 million in 2005... Digital content represents about 20% of supplemental content market, but is expected to grow to beyond 25%. Smaller publishers are showing the most innovation, but these small companies are likely to be gobbled up by the larger players. Sales of tutoring services to schools has been growing by 17% a year."
