Here’s a snapshot of the state of television 70 years ago this month, Agusut 1948, from that month’s edition of Televiser magazine.  New York was still the nation’s hotspot when it came to the new medium, with just over half of the nation’s sets in the New York metropolitan area.

Minneapolis-St. Paul now boasted 5600 sets, 3900 in private homes, with the remaining 1700 in public places.

According to the magazine, over 64,000 sets were rolling off the assembly lines each month.  By comparing with the previous year’s numbers, it was clear that TV was growing fast.  In September 1947, the same survey had shown just over 93,000 sets, with well over half in the New York area.  Minneapolis and Milwaukee hadn’t appeared in the 1947 survey, but were now growing TV markets.
