I'm not sure if I'm just experiencing the higher side of things, but these numbers seem low, or outdated. Friends at several of these companies have been paid on average, about $1,000 or so more than reported here for internships, excluding stipends for travel/living.

Other industries are catching up too. Several of the US investment banks have been paying their interns around the same range, with some going much higher. Lenard Green & Co (leonardgreen.com) is apparently paying at least one intern 140 pro-rated for the summer.

Disclaimer: this may be hearsay and completely false, but these sources have little reason to lie.
