Famous quotes containing the words video, elementary and/or stream:
“It is among the ranks of school-age children, those six- to twelve-year-olds who once avidly filled their free moments with childhood play, that the greatest change is evident. In the place of traditional, sometimes ancient childhood games that were still popular a generation ago, in the place of fantasy and make- believe play . . . todays children have substituted television viewing and, most recently, video games.”
—Marie Winn (20th century)
“As if paralyzed by the national fear of ideas, the democratic distrust of whatever strikes beneath the prevailing platitudes, it evades all resolute and honest dealing with what, after all, must be every healthy literatures elementary materials.”
—H.L. (Henry Lewis)
“This land is your land, this land is my land,
From California to the New York Island.
From the redwood forest to the Gulf Stream waters
This land was made for you and me.”
—Woody Guthrie (19121967)
