Google has unveiled its updated logo for the company’s core search services.

The changes smooth out some of the features in the letters that make up the well-known colorful logo spelling out its name.

Google said the change was needed because people were now reaching Google on lots of mobile devices rather than just desktop computers.

The logo change comes after Google put its many divisions under an umbrella company called Alphabet.

The company said that the logo, and its many variations, would work better on the many different-sized screens through which people used or encountered Google and its services. As well as the full logo of the company’s name, it also plans to use four dots in its signature blue, red, yellow and green colors and a single, multi-colored capital “G” to represent it.

Google announced the change on its official blog and illustrated what was different via a series of animated gifs. It said the revamped logo was “simple, uncluttered, colorful, friendly” and represented the best of Google.

The company also provided a much more detailed explanation of what drove it to change the logo. One key challenge for the designers, it said, was to refine “what makes us Googley”.

Google last updated its logo in September 2013.
