 Exhibit 4.6(i) 
 EIGHTH SUPPLEMENTAL INDENTURE 
 Supplemental Indenture (this “Supplemental
Indenture”), dated as of June 17, 2013, between G4 Analytics, Inc. (the “Guaranteeing Subsidiary”), an affiliate of Nielsen Finance LLC, a Delaware limited liability company and Nielsen Finance Co., a Delaware
corporation (the “Issuers”), and Law Debenture Trust Company of New York, as trustee (the “Trustee”). 
 W I T N E S S E T H 
 WHEREAS, the Issuers and the Guarantors (as defined in the
Indenture referred to below) have heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of October 12, 2010, providing for the issuance of an unlimited aggregate principal amount of Senior
Notes due 2018 (the “Notes”); 
 WHEREAS, the Indenture provides that under certain circumstances the
Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuers’ Obligations under the Notes and the Indenture on the
terms and conditions set forth herein and under the Indenture (the “Guarantee”); and 
 WHEREAS, pursuant to
Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. 
 NOW
THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as
follows: 
 (1) Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to
them in the Indenture. 
 (2) Agreement to Guarantee. The Guaranteeing Subsidiary hereby agrees as follows: 

(a) Along with all Guarantors named in the Indenture, to jointly and severally unconditionally guarantee to each Holder of
a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that:

 (i) the principal of and interest, premium and Additional Interest, if any, on the Notes will be promptly paid
in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or the Trustee hereunder
or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors and the Guaranteeing Subsidiary shall be
jointly and severally obligated to pay the same immediately. This is a guarantee of payment and not a guarantee of collection. 







 (b) The obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment
against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. 

(c) The following is hereby waived: diligence, presentment, demand of payment, filing of claims with a court in the event
of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever. 
 (d) This Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, the Indenture and this Supplemental Indenture, and the Guaranteeing Subsidiary accepts
all obligations of a Guarantor under the Indenture. 
 (e) If any Holder or the Trustee is required by any court
or otherwise to return to the Issuers, the Guarantors (including the Guaranteeing Subsidiary), or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid either to the
Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 
 (f) The Guaranteeing Subsidiary shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. 
 (g) As between the Guaranteeing Subsidiary, on the one hand, and the Holders and the
Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 of the Indenture for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6 of the Indenture, such obligations (whether or not due and
payable) shall forthwith become due and payable by the Guaranteeing Subsidiary for the purpose of this Guarantee. 
 (h) The Guaranteeing Subsidiary shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under this
Guarantee. 
 (i) Pursuant to Section 10.02 of the Indenture, after giving effect to all other contingent
and fixed liabilities that are relevant under any applicable Bankruptcy or fraudulent conveyance laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under Article 10 of the Indenture, this new Guarantee shall be limited to the maximum amount permissible such that the obligations of such Guaranteeing Subsidiary under this Guarantee will not
constitute a fraudulent transfer or conveyance. 
 (j) This Guarantee shall remain in full force and effect and
continue to be effective should any petition be filed by or against the Issuers for liquidation, reorganization, should the Issuers become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for
all or any significant part of the Issuers’ assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any 

  
 2 








 
time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes and Guarantee,
whether as a “voidable preference”, “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned,
the Note shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 

(k) In case any provision of this Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 (l) This
Guarantee shall be a general unsecured senior obligation of such Guaranteeing Subsidiary, ranking pari passu with any other future Senior Indebtedness of the Guaranteeing Subsidiary, if any. 

(m) Each payment to be made by the Guaranteeing Subsidiary in respect of this Guarantee shall be made without set-off,
counterclaim, reduction or diminution of any kind or nature. 
 (3) Execution and Delivery. The Guaranteeing Subsidiary
agrees that the Guarantee shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

called the “Successor Person”); 
 (B) the Successor Person, if other than the Guaranteeing
Subsidiary, expressly assumes all the obligations of the Guaranteeing Subsidiary under the Indenture and the Guaranteeing Subsidiary’s related Guarantee pursuant to supplemental indentures or other documents or instruments in form reasonably
satisfactory to the Trustee; 
 (C) immediately after such transaction, no Default exists; and 

(D) the Issuers shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating

another Guarantor or the Issuers. 
 (5) Releases. The Guarantee of the Guaranteeing Subsidiary shall be automatically
and unconditionally released and discharged, and no further action by the Guaranteeing Subsidiary, the Issuers or the Trustee is required for the release of the Guaranteeing Subsidiary’s Guarantee, upon: 

(1) (A) any sale, exchange or transfer (by merger or otherwise) of the Capital Stock of the Guaranteeing Subsidiary
(including any sale, exchange or transfer), after which the Guaranteeing Subsidiary is no longer a Restricted Subsidiary or all or substantially all the assets of the Guaranteeing Subsidiary which sale, exchange or transfer is made in compliance
with the applicable provisions of the Indenture; 
 (B) the release or discharge of the guarantee by the
Guaranteeing Subsidiary of the Senior Credit Facilities or the guarantee which resulted in the creation of the Guarantee, except a discharge or release by or as a result of payment under such guarantee;

transaction have been complied with.

stockholder of the Guaranteeing Subsidiary shall have any liability for any obligations of the Issuers or the Guarantors (including the Guaranteeing Subsidiary) under the Notes, any Guarantees, the Indenture or this Supplemental Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting Notes waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.
