What kind of media institution might distribute my product?

I have done research on publishing houses that would be the idealist publishing media group for the institution of my horror magazine. In doing so, I have started to evaluate the PROS and CONS of using these publishing houses for my upcoming horror magazine.

A subsidiary company of the large US based publishing corporation Time Inc., IPC Media is the UK's leading consumer and digital media publisher with over 60 iconic brands that vary from LOOK Magazine to NME to Super Yacht World.  

PROS

With a monthly intake of 25 million viewers on their consumer websites as well as attracting two-thirds of UK women and 42% UK men, their advertising can be advantageous to increase a consumer's magazine intake. The opportunity to be part of a publishing house like IPC would be mutually beneficial for both the publisher as well as the consumer product(synergy).  The large UK based conglomerate that is IPC would create more opportunities for convergence like advertisements, as well as funding for media product in addition.

CONS

Working with a large conglomerate can mean constriction of information, which may reduce target audience appeal to my media product.

  - Time Warner is a large multinational publishing company that own Entertainment Weekly. The magazine Entertainment weekly covers popular culture and so the Scream feature in the issue above is more likely to attract a niche audience of horror as well as a mainstream demographic of magazine readers. 

PROS
Having Entertainment Weekly being backed by a large US based media institution like Time Warner can be advantageous for example as the magazine has more funding, and the mutual benefit of advertising for Time Warner will attract more people to the magazine as well as the publishing company- an example of synergy.

CONS
The disadvantage is that being part of a large conglomerate may constrict Entertainment Weekly from being independent and divulge in user generated content.
