On October 18th, 1954 the first commercially available transistor radio went on sale. The TR-1 was produced by Texas Instruments. $51.10 in 1954 is roughly equivalent to $490 today!

The Intel 4004 was made possible because of Bob Noyce's Rubylith process. This was all cut by hand. Pretty neat!

It’s the world’s first #CPU! Wow, seeing this historic chip first time with my own eyes is an unforgettable experience. Decapping went flawlessly, no bond wires damaged. And here it is X, the top metal layer of the 4004, Intel 1971, how cool is that!!!

I like to doodle as I explain things. I always end up doodling something like this on paper every time someone asked me about how to start a project/build a game studio. So I thought sharing this as an infographic might be useful for aspiring indie gamedevs out there.
