It's about as much as a MP3 Song
(a.k.a. MPEG-1 Audio Layer 3, a.k.a. MPEG-2 Audio Layer 3) (128 Kbps, "near-CD-quality"; 3 minutes duration; average)
A three-minute song of typical quality will be about 30,000,000 bits when encoded into MP3 format. The song Tom's Diner by Suzanne Vega was used by AT&T-Bell Labs engineer Karlheinz Brandenburg to test the compression process and is considered the first MP3 song.
It's about two-thirds as much as The Complete Works of William Shakespeare
In other words, 30,000,000 bits is 0.67 times the amount of The Complete Works of William Shakespeare, and the amount of The Complete Works of William Shakespeare is 1.5 times that amount.(ASCII, plain text)
The Complete Works of William Shakespeare would occupy about 44,000,000 bits when written in plain text without formatting. These works include 38 definitively-attributed plays — 11 tragedies, 17 comedies, and 10 tragedies — as well as 154 sonnets and numerous other poems.
It's about two-and-a-half times as much as a Digital Photo
In other words, 30,000,000 bits is 2.4 times the amount of a Digital Photo, and the amount of a Digital Photo is 0.42 times that amount.(5.3 megapixels, JPEG compression, 100% quality, 24 bits/pixel)
A 5.3-megapixel digital camera photo requires about 13,000,000 bits of storage space. In 2010, it was expected that 90% of all professionally-taken photographs would be digital instead of film.
It's about two-and-a-half times as much as a Floppy Disk (3½-in)
In other words, 30,000,000 bits is 2.54313 times the amount of a Floppy Disk (3½-in), and the amount of a Floppy Disk (3½-in) is 0.393216 times that amount.(high density, IBM PC format)
Despite common reference to them as "1.44" megabyte (mB) disks, the actual capacity of the most common model of a 3&-in (8.9 cm) floppy disk is 11,796,500 bits. At the height of their use 1996, there were an estimated five billion disks in use — nearly one for each person on Earth at the time.
It's about one-two-hundredth as much as a Compact Disc
In other words, 30,000,000 bits is 0.00485 times the amount of a Compact Disc, and the amount of a Compact Disc is 206.1 times that amount.(80-minute, 360,000 sector disc; "Red Book" specifications)
A typical, 80-minute capacity compact disc, commonly known as a 5,872,000,000 bits disc will actually hold 6,185,000,000 bits of data. Such disks are 1.2 mm (0.047 in) thick.
It's about one-one-thousandth as much as an HDTV Television Show (30 Minutes)
In other words, 30,000,000 bits is 0.00083 times the amount of an HDTV Television Show (30 Minutes), and the amount of an HDTV Television Show (30 Minutes) is 1,210 times that amount.(a.k.a. High Definition television, a.k.a. HD) (digital signal, QAM-256; 30 minutes)
Broadcast cable HDTV signals contain about 20,100,000 bits of data per second, or 36,200,000,000 bits in a thirty-minute television show. The first High Definition television broadcast was news footage from John Glenn's 1998 mission on the space shuttle Discovery.
It's about one-one-thousand-five-hundredth as much as a DVD
In other words, 30,000,000 bits is 0.0008 times the amount of a DVD, and the amount of a DVD is 1,300 times that amount.(a.k.a. digital video disc) (single-side, single-layer; DVD-5 specification)
A typical capacity digital video disc will hold 40,000,000,000 bits of data. Such disks are 1.2 mm (0.047 in) thick.
