Mark Cuban, the always-entertaining president & chairman of HDNet and owner of the Dallas Mavericks, offered a very plausible theory today about what’s driving ABC-Disney’s decision to broadcast its most popular shows over the Internet. While at Broadcast.com in 1998, Cuban fielded research in which 93% of respondents said the computer was the primary media device in the office. “And that was 1998,” he stressed today, suggesting that the percentage would certainly be even closer to 100% now. “So, if I missed ‘Desperate Housewives’ last night, I’m just going to watch it at work.” The audience at the National Show session laughed, then laughed even harder when Cuban’s fellow panelist, Insight Communications President & CEO Michael Willner, replied emphatically, “There will be absolutely no watching of ‘Desperate Housewives’ within any of the Insight offices between 9 to 5.”
