If the 33&1/3 rpm vinyl record was presented a birthday cake, it would have 70 candles!

The long play record (LP) was developed by CBS Laboratories, and introduced to the world by CBS' Goddard Lieberson on June 20th, 1948.

First, some quick history:

Since the beginning of the phonograph, most records (10-inch, 78-rpm discs used since the 1890's) played for about two or three minutes.

Occasionally, the various record companies issued 12-inch (shellac) records, which had a bit more capacity (78-rpm song-playing time).

78's were also easily breakable!

But, that was about to change...

As "luck" would have it, CBS and competitor RCA, were both working to improve the record, by the mid-1940's!

RCA's concept stuck to the long-standing notion that a record should not have to hold more than one song.

RCA reduced speed to 45-rpm, and used a finer groove, in the effort to develop a smaller disc than the 78-rpm standard. RCA also used a new plastic material, called vinylite, which resulted in the needle picking up less surface noise and hiss.

World War II interrupted research and development...

...but the new 45-rpm disc and its player were introduced at the end of 1947.

At the same time:

CBS research director Peter Goldmark, and other engineers were developing the 12-inch, 33&1/3-rpm, long playing record (LP).

It was also made of vinyl plastic, and had very fine grooves.

The concept behind CBS's LP was different from RCA's offering: with its slower speed and larger diameter, the "Long Playing" record was originally designed to showcase classical music, which often ran for 20 minutes or more without a break.

So, after June 20, 1948, consumers had two "new and improved" types of records:

One standard emphasized single songs, the other suited for multiple songs, or long-playing single programs. However, each used different, non-compatible playback equipment.

Naturally, within a few years, most record companies had adopted both the LP and the 45-rpm formats.

Engineers easily adapted record players to accommodate both types of discs, as well as the older 78-rpm singles!
As a side note, as a kid, I had a "record player" that once belonged to an elementary school...it also played 16-rpm records! These slow-turning vinyl records were for instructional purposes. Fidelity was poor...but that was fine...as these were spoken word ("talking") records.

With the superior sound...

...and equipment compatibility, you would think that the old-fashioned 78-rpm record vanished QUICKLY...but NO!

The major labels didn't totally phase out the 10-inch, 78-rpm disc until...1958!! AMAZING!

The growth of LP sales in the 1960's and 1970's transformed the record business, generating large profits, and the LP restored the industry to the prominence it had held in the early 1920's, before radio was introduced.

The birthday-celebrating vinyl LP was hurt by the introduction of the compact disc in the early 1980's...

Most major label record companies stopped releasing vinyl in large amounts, by the early 1990's.

Happily, that's not the end of the story: LP's (and 45's) are still being produced!

Vinyl thrives in underground music scenes and niche collector markets, and is still commonly used by New Jersey club DJ's for mixing purposes.

Within the last few years, vinyl has experienced a resurgence in the mainstream, with some of today's top-40 artists issuing their albums in vinyl formats...

And, selected "Greatest Hits" can now be enjoyed on high quality "Audiophile" vinyl, too!

You have to look for new vinyl...and...

...be prepared to...

...pay the price...literally.

Or...pick up an LP at a "used record store."

Or...inherit it!

In any event:

Happy 70th to the LP!

And, many more!
