Can you help me compile a list of (fictional) companies, that star in TV series?

From the 50’s till today; can you come up with company names that were/are starring in television series.
Preferably from comedies, but other genres are okay too.
From America, and the UK, but series from other countries are also okay, as long as as they were/are widely known.

For example:

Dunder Mifflin – The Office
The Bluth Company – Arrested Development
Gary’s Shoes & Accessories for Today’s Woman – Married With Children

Thanks in advance!
