July 1934 Radio News & Short-Wave

Have you seen the new
national advertising campaign where Freescale (formerly Motorola) is using big name
celebrities to sell their cellular base station power transistors?
Scarlett Johansson and
Ashton Kutcher are up on a tower along with man-and-woman-on-the-tower
smartphone users discussing how much better their phones work now that the service
provider switched to base transceiver stations (BTSs) that use Freescale LDMOS RF
power transistors. Of course you haven't seen the ad because it would never be produced
and marketed. The very concept is ridiculous, you might say... unless you happened
to see advertisements like this one for RCA's Radiotron vacuum tubes from the 1930s.
In it, none other than Bing Crosby was joined by a trendily dressed woman who was
rejoicing in her decision to buy a new radio that contained those newfangled "Micro-Sensitive"
receiver tubes. Now, raise your hand if you would
like to see an advertisement with Scarlett Johansson and/or Ashton Kutcher on top
of a cell tower.
