   • 2013 July 20, “The attack of the MOOCs”, in The Economist, volume 408, number 8845:

     Since the launch early last year of […] two Silicon Valley start-ups offering free education through MOOCs, massive open online courses, the ivory towers of academia have been shaken to their foundations. University brands built in some cases over centuries have been forced to contemplate the possibility that information technology will rapidly make their existing business model obsolete.

   It is speculated that, within a few years, the Internet's speedy delivery of news worldwide will make newspapers obsolete.

   Synonyms: antiquated, deprecated, disused,

2. (biology) Imperfectly developed; not very distinct.
