Dial Up Internet
It might sound really awkward but only 5% (almost 10 million) of the American adults are connected to the Internet. Well, they are linked via the modem, which is the modulator and demodulator. And the speed at which they surf the internet is only 50.6 Kbps (or even slower). As a side note, only 6% of the Americans live in areas without broadband access and those 4% mentioned above are probably unable to meet the expenses or are too avaricious to pay for high-speed services.
