JADIO NEWS ANDHo JUNE SHIRT WAVE RADIO www.americanradiohistory.com NCB AGAIN We Thank You! THIS issue marks the 17th Anniversary of RADIO NEWS -radio's oldest semi -technical publication. And we, the staff of RADIO NEWS, wish to extend to you, our readers and advertisers, our sincere thanks for your valued patronage which has made this long life possible. EVER since 1919 -a year before regular broadcasting began -when a crystal receiver that brought in a few, weak, nearby stations amidst the roar of static was something to brag about -RADIO NEWS has been the alert observer for tens of thousands of radio men -accurately reporting and de- scribing each new development in the saga of radio progress. NOW, we stand at the threshold of a new era -the age of television. And again, RADIO NEWS stands prepared to bring you each new development as it springs into being. You may rest assured that so long as the fertile minds of radio experts create new radio devices and theories, RADIO NEWS will report them to you accurately and concisely. WE consider it a solemn trust to ever aid in the advance- ment of radio. The past has proven the value of this - many of our readers who were "beginners" 17 years ago are now leaders of the radio industry. AT this, the beginning of our 18th year, we again pledge to continue our editorial policy of publishing all the impor- tant news of every branch.. of radio -in the same friendly,, factual manner as we have always done. W E like to think of RADIO NEWS not as a commercial proposition but as the "eyes and ears" for our many radio friends. It is your publication -without your constant patron- age it could not exist. Help us make it even more valuable -by telling your friends and neighbors about the features you like. Only thru this cooperative spirit can we continue to advance -for you, our radio friends, are the batckbone of this publication.
