NEW YORK ( TheStreet) -- It's Social Media Day, and over 15,000 people have already tweeted about the happening today. The day is a celebration of the impact social media can have on global communication, according to Mashable, which drummed up the idea some six years ago.

So, in celebration of social media, or at least in acknowledgement of its presence in our lives, TheStreet has compiled a list of the best CEOs and business leaders to follow on Twitter. Some were included because they break news for their companies while others were chosen because their commentary about events, happenings, corporate actions is often news by itself.

Here, in no particular order, is our list:

Eddy Cue is Apple's (AAPL) - Get Report senior vice-president of Internet software and services and the man behind Apple Music. While Cue may not have as many followers as his boss, CEO Tim Cook, his Twitter feed is more engaging and personal. Last week, Cue was given the task of breaking the news that  Apple would pay artists during Apple Music's three-month trial period. Hallelujah.

Richard Branson
Handle:  @RichardBranson
Followers: 5,990,000

Richard Branson is the eccentric CEO of Virgin Group, which once served ice cubes shaped like his face on some of the company's flights. And his twitter feed doesn't disappoint. Branson tweets about everything from throwing the first pitch at a Detroit Tigers baseball game to his newest business ventures. Branson's account is crucial insight for investors in Virgin Group, and its various businesses, as a provides a direct line from the CEO's brain to the public.

Jack Dorsey
Handle:  @jack
Followers: 3,040,000

Being a co-founder, and as of June 11, interim CEO, of Twitter  (TWTR) - Get Report apparently means you get to pick your twitter handle before all the other Jacks in the world. As the CEO of two major companies, Dorsey also heads the payment company Square. The dual perch affords Dorsey clout and distinction and his twitter feed is often filled with news about his company and insights into related industries. Dorsey also tweets links to personal interests like a new Netflix documentary, or the latest app he has downloaded.

Elon Musk
Handle:  @elonmusk
Followers: 2,310,000

The best explanation of what's happening at SpaceX and Tesla, comes from one of Musk's tweets. Immediately following the explosion of the SpaceX Falcon 9 launch, Musk was on Twitter providing the first public statement for the company and promising updates as new information was gathered. Investors in any of Musk's companies should keep an eye on his account for breaking news and insights on technology and transportation of all sorts.

Donald Trump
Handle:  @realDonaldTrump
Followers: 3,070,000

Donald Trump has made a lot of headlines recently. His incendiary, some would say racist, remarks made during his presidential candidacy announcement on June 16 prompted  Univision, Comcast's  NBC and Mexico's Televisa to cut ties with the businessman. Trump's Twitter account acts as his personal bullhorn, as Trump reacts to criticisms directly through his account.

Bill Gates
Handle: @BillGates
Followers: 23,100,00

The founder and former CEO of Microsoft does not hint at his tech legend stats on Twitter. Gates' bio reads "Sharing things I'm learning through my foundation work and other interests..." with a link to his personal blog. As co-founder of the Bill and Melinda Gates foundation, Gates has devoted his twitter to his philanthropic work, with the occasional comment on current events and business news.

Carl Icahn
Handle: @Carl_C_Icahn
Followers: 230,000

The activist investor has a wealth of financial information in his Twitter feed. Most recently, Icahn tweeted about selling out of his Netflix (NFLX) - Get Report position after the company announced a stock split. Netflix, which was soaring before the tweet, promptly took a dip. Icahn regularly tweets about his investments, and investors should be watching his feed.

Rupert Murdoch
Handle:  @rupertmurdoch
Followers: 583,000

Rupert Murdoch recently announced his departure as CEO of 21st Century Fox (FOXA) - Get Report, but that doesn't mean he can't offer insights into his thinking and news from the family business. Murdoch also offers personal and political opinions on his Twitter, in addition to his business musings. 

Oprah Winfrey

Oprah Winfrey
Handle:  @Oprah
Followers: 28,100,000

Oprah isn't the first name that comes to mind when thinking of business leaders, but with more followers than anyone else on this list she has a strong following and a large influence. Winfrey's feed mostly consists of her interacting with followers and promoting her network, but she does provide business and personal insight on occasion.

David Karp
Handle:  @davidkarp
Followers: 42,500

David Karp is not your average business leader, but he is the CEO of Tumblr, the micro-blogging site which he sold to Yahoo! for $1.1 billion in 2013. Karp's Twitter reads much like his Tumblr blog, it's filled with GIFs of dancing robots and photos with snarky captions. The CEO doesn't offer much business value through his feed, but he is entertaining.

Aaron Levie
Handle: @levie
Followers: 155,000

Aaron Levie is the CEO of Box (BOX) - Get Report, which went public earlier this year. The cloud-based storage company is headed by a leader who isn't afraid to let his personality shine through, as his Twitter is a mix of news from Box.com and his own commentary on current events.
