Depends on what you consider a monopoly, and where you live. I know in some regions I have lived previously, my low-latency internet options, as allowed by city ordinance, were ADSL (128kbit) from a single company allowed to operate phone lines in the area, or cable service from a single company allowed to operate in the area. My high bandwidth options were satellite (download bandwidth only, as upload would have been via a phone-line modem of some sort through the above-mentioned single phone company allowed to service the region) or cable. If I wanted both low latency and high bandwidth (or high upload bandwidth), there was only a single cable company allowed to offer that service. That sounds suspiciously close to a government granted monopoly (or duopoly, if you prefer).
