By 2010, an average household with 2 standard definition TVs, one HD TV and two computers will be using 1.1 terabyte of data a month, according to Ken Wirt, vice president of consumer marketing for Cisco Systems. Wirt was kind enough to chat with me about this statistic along with another eye-popping number about the coming wave of Internet video use (hint: exabytes, baby). Think Comcast and Time Warner will raise those caps?
