There were billions of dollars funding work on paid network traffic prioritization in the 90s and early 2000s. Then the whole field was banned in 2005, and it evaporated. The ban was lifted in 2008, then reapplied, then lifted again in 2014, then reapplied in 2015, then lifted again. Vast amounts of money flowed into and out of the sector at each reversal.
