The online education sector grew 13% last year and had been growing at about 20% in previous years. Nearly one in four students take at least some college courses online, up from one in 10 in 2002. Two million students, most older than the traditional 18-22 year-old undergraduates, take all their courses online and two million more take one or more online course. President Barack Obama pledged $500 million for online courses and materials as part of a multi-pronged plan aimed at expanding access to college.
