Past and Present Technology: Then and Now Infographic

An infographic comparing past and present technology typically shows a side-by-side timeline of devices like the rotary phone versus the smartphone, the CRT television versus the OLED flat screen, or the floppy disk versus the cloud. The goal is to highlight how the core function of each device has stayed the same while the form factor, speed, capacity, and user interface have radically evolved. This article explains what these comparisons usually include, why they resonate, and how to read them critically.

Why Infographics Compare Then and Now

Infographics are visual tools that condense complex changes into a single glance. The “then and now” format works because it triggers recognition: viewers already know what a landline phone or a VHS tape looks like, even if they have not used one in decades. By placing the old and new side by side, the designer makes the abstract concept of technological progress concrete. Common comparisons include:

• Communication: rotary phone vs. smartphone (features, not just calling)
• Data storage: floppy disk vs. SSD or cloud storage
• Media playback: vinyl record vs. streaming service
• Photography: film camera vs. digital mirrorless
• Computing: room-sized mainframe vs. laptop
• Navigation: paper map vs. GPS app

Each pair highlights a specific dimension of change: size, speed, capacity, cost, or accessibility. The best infographics do not just show a bigger number; they explain what that number means for daily life.

Key Metrics in Then-and-Now Comparisons

When you look at an infographic, pay attention to which metric is being compared. Often it is one of the following:

• Storage capacity: megabytes vs. gigabytes vs. terabytes. A 1.44 MB floppy holds about one high-resolution photo today.
• Processing speed: clock speed (MHz vs. GHz) or instructions per second. The Apollo Guidance Computer ran at 0.043 MHz; a modern smartphone exceeds 3 GHz.
• Physical size: a 1980s hard drive weighed over 5 kg and stored 10 MB; a microSD card weighs less than a gram and stores 1 TB.
• Cost per unit: the first 1 GB hard drive in 1980 cost about $40,000 (adjusted for inflation); today a 1 TB external drive costs a fraction of that.
• Energy consumption: an old CRT monitor used about 100 W; an LED monitor of similar size uses about 30 W.

Always check the year and the exact model. A 1990 “computer” is very different from a 1970 one. Infographics sometimes cherry-pick the most extreme examples to make the contrast look bigger.

How to Read an Infographic Critically

Infographics are designed to persuade as well as inform. Here are common pitfalls to watch for:

• Mixing units: comparing a 1.44 MB floppy to a 64 GB USB drive without converting units is misleading. Always convert to the same unit (e.g., MB).
• Ignoring context: a 1980 computer with 64 KB of RAM was impressive for its time; comparing it to a modern phone without noting the different software demands is unfair.
• Linear vs. logarithmic scale: a chart that uses a linear scale makes a jump from 1 to 100 look the same as 100 to 199, even though the first is a 100x increase and the second is only 2x. Logarithmic scales show relative change more honestly.
• Selective timeframes: starting at the very first model makes the change look huge; starting at a model from 10 years ago makes it look small.

A good infographic will state the years, the exact models, and the units. If it does not, treat the numbers with caution.

Common Misconceptions

One frequent misconception is that “old technology was slower” in every way. In reality, a mechanical typewriter can be faster for a skilled user than a touchscreen for some tasks, and a landline phone has better audio quality than a cellular call in many cases. The change is not always linear improvement; it is a trade-off. Another misconception is that storage capacity always increases. While that is true for most consumer devices, some formats (like the 3.5-inch floppy) were replaced by CDs (700 MB) which were then replaced by DVDs (4.7 GB) and then by streaming, where local storage is irrelevant. The infographic should show the direction of change, but the underlying story is about trade-offs, not just “bigger is better.”

How to Make Your Own Then-and-Now Infographic

If you want to create a comparison, follow these steps:

1. Choose a specific device or service, not a broad category like “computer.”
2. Pick two concrete models with known release years and specifications.
3. Decide on 3-4 metrics to compare (size, weight, capacity, speed, price).
4. Convert all units to a common base (e.g., MB for storage, GHz for speed).
5. Use a visual that shows relative size (e.g., a floppy disk next to a microSD card is a classic).
6. Add a short caption explaining the real-world impact of the change.

For example, compare the 1981 IBM 5150 (16 KB RAM, no hard drive, 25 kg) to a 2023 smartphone (12 GB RAM, 1 TB storage, 200 g). The smartphone is about 750,000x more RAM and 1,000,000x more storage, but it also fits in a pocket. That is the kind of concrete detail that makes an infographic memorable.

Frequently Asked Questions

What is the most common comparison in then-and-now infographics?

The most common is the smartphone versus the personal computer, or the floppy disk versus the USB drive. These are visually recognizable and have dramatic differences in capacity and size.

Why do infographics often use logarithmic scales?

Because technological growth is often exponential. A linear scale would make a 1 TB drive look only slightly larger than a 1 GB drive, even though it is 1,000 times bigger. A logarithmic scale makes the relative jump visible.

Are old technologies always worse than new ones?

No. Some old technologies had advantages: vinyl records have a warmer sound to some ears, mechanical keyboards are preferred by many typists, and film cameras have a distinct aesthetic. The infographic usually focuses on measurable specs, not subjective qualities.

How do I convert between MB, GB, and TB?

Use the base-2 or base-10 convention. Most storage manufacturers use base-10: 1 GB = 1,000 MB, 1 TB = 1,000 GB. Operating systems often use base-2: 1 GB = 1,024 MB. Always check which convention the infographic uses.

What is the best source for accurate specs of old devices?

Museum archives, manufacturer datasheets, and reputable tech history sites like the Computer History Museum. Wikipedia is a good starting point but verify with primary sources for exact numbers.
