McDonald's

Background
McDonald's is an American multinational fast food chain and real estate company, founded in 1940 as a restaurant operated by Richard and Maurice McDonald, in San Bernardino, California, United States. They rechristened their business as a hamburger stand, and later turned the company into a franchise, with the Golden Arches logo being introduced in 1953 at a location in Phoenix, Arizona.

Logo (2019?)
Logo: At the end of the commercial, we see the famous Golden Arches draw themselves while a red square zooms out with the emblem resulting in a symbol similar to the McDonald's app logo. The tagline "i'm loving it" appears below.

FX/SFX: 2D Animation

Music/Sounds: Tons of variants of the classic McDonald's jingle. The 2 most common ones are a whistled version of the theme or a man with a deep voice voicing the jingle.

Availability: Seen on their modern commercials.
