90s kid memories • cable internet origin story

I’m Not Old — I Watched the Internet Get Installed

Backhoes, giant coax, and “future services” that turned into broadband.

One of my most specific “90s kid” memories isn’t a TV show or a toy — it’s standing outside watching the cable company tear up the neighborhood. I remember the trencher, the fresh dirt, the orange cones, and those giant spools of coax that looked way too serious for “just TV.” It was the kind of infrastructure that made a kid stop and stare because it felt like something important was happening.

I was told back then it was for internet — for “the future.” The crew answers were always vague, like they were trained to say the same line:

“Future services.”

At the time, that phrase sounded like marketing fog. But a few years later, cable modems showed up and the fog cleared: that trenching was the physical foundation of broadband. The internet didn’t magically appear — it got installed.

What Was Actually Happening (The Non-Marketing Version)

Cable TV networks were originally designed as a one-way broadcast system: signals go out, everyone receives them. Internet requires two-way traffic — your computer has to talk back. So in the 90s, cable companies started upgrading their “plant” so it could handle both directions and higher quality signals.

🧩 Quick mental model: Hybrid Fiber-Coax (HFC)

Headend

Cable company core

➜

Fiber trunk

Light to the neighborhood

➜

Optical node

Light → RF

➜

Coax plant

Copper to houses

Translation: most neighborhoods got fiber to a local node, then coax the rest of the way. The big cable you saw trenched was likely part of that coax distribution rebuild — the “last mile” TV infrastructure becoming a data network.

How Early Cable Modems Worked (In Human Language)

Early cable modems weren’t just “Ethernet devices.” They were more like a TV tuner and a radio modem combined. The network used RF channels (the same kind of spectrum used for cable TV), and everyone in the neighborhood shared it.

• High frequency RF channel(s)
• Everyone listens
• Your modem filters what’s “for you”
• Fast compared to upstream

• Lower frequencies (noisier)
• Shared “talk-back” channel
• Modems take turns transmitting
• Historically the weak link

In the late 90s, the industry standardized around DOCSIS (the CableLabs spec that made cable modems interoperable). That’s when cable internet stopped being a chaotic science project and became a scalable product: authentication, provisioning, and managed speeds.

The 90s Kid Part: We Saw the Seam

What makes this feel so “90s kid” isn’t just the tech — it’s that we watched the transition happen in public. Infrastructure wasn’t hidden. Progress had a soundtrack: trucks, compressors, trenchers, and the constant beep-beep of heavy equipment reversing.

📼 90s kid sensory checklist (if you know, you know)

• Standing outside watching crews work because it was actually interesting
• Everyone asking “what are they putting in?” and getting vague answers
• Dial-up sounds inside the house, construction sounds outside
• Then one day: always-on internet, like a cheat code

And the part that’s equal parts funny and existential: a lot of that buried coax is still there. It might be reused, re-terminated, amplified differently, or partially replaced — but the “future services” foundation is still under the street.

So… Am I Old?

Maybe a little. But mostly I’m just time-privileged. I didn’t read about broadband arriving — I watched it get installed. The internet wasn’t a cloud. It was dirt, cable, and a crew saying “future services” like a prophecy.
