Reveals a Renaming!

A List of the Ten Most Valuable Brands in the World This Financial Year:

1. Amazon;

2. Apple;

4. The Samsung Group;

6. AT&T (American Telephone & Telegraph);

7. Microsoft;

8. Verizon;

9. Walmart; &

10. The Industrial and Commercial Bank of China.

A brief description of each of them:

1. Online retail trailblazer;

2. Computers, phones, TV;

3. Internet web, a mega 'billboard';

5. Think talkathon, fandom, crazy election havoc (hahaha!);

6. Mass media;

7. Software;

8. Communications;

9. Full of popular retail; &

10. Mortgage, finance.

What one word describes how I have named each brand?

There might be many, though I am looking for an $$8$$-letter word that is actually one of the tags on this site! I will include that tag after I have accepted an answer (or else it would spoil the puzzle).

This is not my puzzle, and will provide attribution after I have accepted an answer. For users who've seen (or might have seen) this puzzle before...

...lucky you.

The title is also a clue.

• I'd suggest not including the "answer tag" after it's found. The enigmatic tag is fine by itself and adding the tag would be a spoiler, even when the correct answer is given, right? – Chowzen Sep 22 '18 at 11:50
• @Chowzen yeah, true. Okey, then, if you say so. I have edited the question accordingly :P – Mr Pie Sep 22 '18 at 11:53

the word is

Anagrams

Because

if you take all of letters of the first list, including "A List of the Ten Most Valuable Brands in the World This Financial Year", you can anagram it into the second list

Possible title clue

Title "Reveals a Renaming!" is an anagram of "Anagrams Never Lie".

• (Pedantry alert: This post has "and mega billboard", but it should be "a", not "and".) – M Oehm Sep 22 '18 at 20:58
• @user477343: I don't understand your answer. I tried to point out (without spoilers) that the two lists are not anagrams of each other with "and", because you get an extra n and an extra d. The original has it right. – M Oehm Oct 7 '18 at 7:23
