Roku

Background
Roku is a brand of hardware digital media players manufactured by American company Roku, Inc. The first Roku model, developed in collaboration with Netflix, was introduced in May 2008. Roku devices are considered to have popularized the concept of low-cost, small-form-factor set-top boxes for over-the-top media consumption. Roku has also licensed its platform as middleware for smart TVs.

1st (known) Screen (July 2011-March 2013)
Screen: On a black background, we see the Roku logo in. The letters of the logo bounce one by one.

Technique: CGI.

Music/Sounds: None.

Availability: Extinct. Was introduced with the second generation of Roku products.

2nd (known) Screen (March 2013-Late 2010s?)
Screen: In a dark area with a floor, the letter "R" from the Roku logo swings into view from a web (like Spider-Man), the "O" enters as if it were in the Transporter from Star Trek, the "K" enters from an umbrella (in reference to Mary Poppins), and the "U" is launched into its position, leaving a trail of dots, after it lands, red feathers and dust clouds appear, and the number "5000" pops above it (in reference to Angry Birds). After this sequence, the "R" and "O" look around the area, the "K" taps its "foot", and the "U" doses off, quickly wakes up, and shakes its "head", this is looped until the device has fully loaded. Technique: CGI by Jeff Anderson.

Music/Sounds: Sounds corresponding to the animation, a descending synth theme, and a ding when the number "5000" appears, after the main sequence, elevator music quietly plays.

Availability: Extinct. Was introduced with the Roku 3.

Screen: On a diamond-pattern background, we see the the TCL logo and the Roku logo in white, with a dot in between both logos.
