In July 1995, the moment finally arrived: the MP3 format, also known as MPEG-1 Audio Layer III, was unveiled. Developed by Fraunhofer researchers Ernst Eberlein, Heinz Gerhäuser, Bernhard Grill, Jürgen Herre, Harald Popp, and above all Karl Brandenburg, the format offered high audio quality even at low data rates. That made MP3s ideal for a time of modems with speeds of 14.4, 28.8, or 33.6 kbit/s. 30 years of MP3 is a long time ago!

A Venn diagram representing RGB color space, with 256 shades per color channel, would show three overlapping circles, each representing Red, Green, and Blue. The overlapping areas would represent the colors created by mixing two or three of the primary colors. The center of the diagram, where all three circles overlap, would be white, as maximum intensity of all three colors produces white. The areas of overlap between two circles would be cyan (blue and green), magenta (red and blue), and yellow (red and green). 

Here's a more detailed breakdown:
Three Overlapping Circles:
Imagine three large circles, each labeled Red, Green, and Blue, overlapping each other in a way that creates distinct sections.

Center Intersection (White):
The central area where all three circles intersect represents the combination of maximum intensity of all three colors, resulting in white.

Two-Color Overlaps (Secondary Colors):
The areas where two circles overlap represent the secondary colors created by mixing those two primary colors:
Red and Green = Yellow
Red and Blue = Magenta
Green and Blue = Cyan

Single Color Sections (Pure Colors):
The remaining sections of each circle, not overlapping with others, represent the pure primary colors (Red, Green, and Blue) at their various shades.

256 Shades per Channel:
The "256 shades" aspect means that within each circle (representing Red, Green, and Blue), there are 256 different levels of intensity for that color, ranging from 0 (off) to 255 (maximum intensity).

Total Combinations:
With 256 shades for each color, there are a total of 256 x 256 x 256 = 16.777.216 possible color combinations (16.777.216 million colors).

Bluetooth's history beginns in 1994 with Ericsson's project to replace wired connections with a short-range wireless technology, which was named after the 10th-century Danish king Harald Bluetooth, who unified tribes of Denmark and Norway, reflecting Bluetooth's goal of uniting devices. The Bluetooth Special Interest Group (SIG) was formed in 1998 by founding companies Ericsson, Intel, Nokia, IBM, and Toshiba to standardize and promote the technology. The first Bluetooth specification, version 1.0, was released in 1999, and the technology has since evolved with multiple versions and profiles, enhancing data transfer speeds, power management, and audio capabilities. My first personal contact with this technology was at the CEBiT fair in spring 2000, where I worked one week for a promotion team of the BOSCH mobile phone branch, while I was still an EEIT student myself.  https://www.mobilephonemuseum.com/catalogue
