While most people who watched the first live presidential debate saw it on TV, 11 percent also had a second debate-related screen going, either on their computer, smartphone or tablet, watching or reading related coverage at the same time.
The finding is from the Pew Research Center for the People & the Press, which said Thursday that younger Americans, those 40 and under, were most likely to be "dual-screeners."
Pew also reports that 3 percent said they watched the debate online only, either on their computer or a mobile device.
The first debate was Oct. 3; the next presidential debate is Oct. 16. Pew's survey was done Oct. 4-7 among 1,006 adults.
While some debate watchers took to Facebook and Twitter to comment during the event, those folks were in the minority.
Only about a third of those who were following the debate online in real time say they shared their personal reactions to online during the debate, Pew said, "representing 5 percent of the overall debate audience."
