seems to say yes:

"Analyzing new data, drawing on a number of our prior analyses, and reviewing other studies of wages and employment in the STEM and IT industries, we find that industry trends are strikingly consistent: ... Wages have remained flat, with real wages hovering around their late 1990s levels."

EDIT: if you're skeptical of EPI, Brookings also agrees:

DOUBLE EDIT: to echo what I've said in other comments, Brookings disagrees with EPI's findings. PBS selectively quoted them.
