Comment : RCA Victor introduces the 45 rpm 7-inch single with microgrooves.Here is the Apr. 2 1949 Advertisement in Billboard magazine: “THE PLAYER."Read the new RCA-Victor player story in 30 seconds".WORLD'S FASTEST RECORD CHANGER!!-- Trigger-action speed! Can play more than 50 minutes of music without the need of attention. And it's just the music the listener wants when he wants it. It can play up to ten records with speedy, silent, hardly noticeable changes.COMPACT AND LIGHT!! The changer unit occupies less than half the space of other types. This opens entirely new avenues to smarter console cabinet styling...to greater economies and greater values. The lightweight, compact table phonograph model can easily be carried from room to room.SILENT, RECORD-SAVING PICKUP! The new RCA Victor player exerts a stylus pressure of only 5 grams. There's a new "Silent Sapphire" Pickup. No needle changing. Records sound better--last longer. Two vital customer "wants.".BIG PYLON SPINDLE HOLDS CHANGER MECHANISM! Changer mechanism is within the large spindle. No posts or clamps to adjust. Fewer moving parts--it's trouble-free. The new RCA Victor changer is the surest, easiest operating changer ever designed.4 QUICK INSTRUMENT FACTS TO TELL YOUR CUSTOMERS. 1. World's fastest changer. 2. Easiest, surest operating changer ever...and it costs less 3. Automatic...load the spindle--press a button once and that's all. 4. Can play more than 50 minutes without need of attention.THE RECORD.DISTORTION-FREE PLAYING SURFACE. Theoretically, every record can have a "Quality Zone"...a portion of the record in which no distortion occurs. Music recorded beyond this zone is distorted. New RCA Victor records are the first to be recorded entirely in the "Quality Zone"--and they play as long as ordinary 12-inch records.LASTS MANY TIMES LONGER! Made of non-breakable vinyl plastic with a special "Shoulder Construction," the new record lasts up to 10 times longer...cuts inventory losses due to damage in handling and storing. The surface-saving shoulder keeps playing surfaces from rubbing one another...Prevents damage to record grooves.CONVENIENT 7-INCH SIZE! More than 150 single records or 18 symphonies fit in one foot of bookshelf space. No storage problems for your customers. You can display a wider, more complete selection without sacrifice of space.LOW COST CREATES BIGGER MARKET! From the record press to the customer's purse, the 7-inch record costs less...opens a bigger market...new collectors! And those who own ordinary records now find that it takes less money to buy more pleasure. The new 7-inch record ensures you greater profit through faster turnover. Sparkling identifying colors!-- Record classification is simplified because a different color [of the wax record] is used on the entire record... not just on the label to denote each classification. This helps you to determine the type of record at a mere glance: Popular...(Black)--- Classical...(Red)--- Popular Classical...(Midnight blue)--- Children's...(Yellow)--- Country and Western...(Green)--- Blues and Rhythm...(Cerise)--- International...(Sky blue)”. (Cited by Norm Katuna)The vinyl microgroove 33 1/3 RPM 'LP' record was developed and first marketed by Peter Goldmark and his engineers of Columbia records in 1948. Prior to the retail release of the first 33 1/3 'LP' record, Peter Goldmark invited David Sarnoff, the head of RCA, and his engineers to tour the Columbia record labs and view the new 33 1/3 RPM disc and record playing system. David Sarnoff accepted the invitation, and he and his chief engineers were ushered through the Columbia labs by Peter Goldmark, shown the entire new microgroove record cutting lathe and record pressing system, and treated to a sound quality demonstration of the new 'LP' disc. The new vinyl disc was a light years leap ahead in sound quality compared to the only other disc recording medium of the day, the 78 RPM shellac record. The new 33 1/3 RPM 'LP' records provided greatly extended frequency response of 50 to 12,000 cps (cycles per second), compared to the average 8,000 cps top frequency limit for current production 78 RPM discs - plus, the new microgroove records made of vinyl provided very low surface noise, and for the first time quiet music passages were not drowned out by the hiss and scratch surface noise inherent in shellac 78 discs. In addition, the new vinyl records were not breakable, unlike brittle shellac 78 discs - and, a 12 inch vinyl disc weighed a fraction of the weight of a comparable old fashioned 78 disc --- saving the record producer, record shipper and retail record store the hassle and monetary loss from broken 78 discs and a great savings in lowered shipping costs. David Sarnoff and his engineers politely expressed their approval and admiration for the 'new' recording medium developed by Columbia, but following the tour and demonstration, David Sarnoff ordered his engineers in marketing and research to bring into productiion the previously developed RCA Victor 45 RPM system (which had been kept a carefully guarded industrial secret for nearly 10 years). RCA Victor was able to bring their entire 45 RPM record system out of mothballs and into production by early 1949. The first advertising for the new '45' system appeared in Billboard magazine in April 1949, and the first of the new 45 RPM discs and automatic record players appeared in retail record shops in June of 1949. Peter Goldmark and his Columbia record engineers could not understand or believe RCA Victor could develope and bring to market an entirely new disc recording medium in only a few months - and, they did not know for several years that RCA Victor had invented and developed a ready for market 45 RPM record and automatic record changer in 1938 / 1939, a full ten years before Columbia developed the microgroove 33 1/3 system.
